By extending their unbeaten run to nine games, Leicester officially knocked Manchester City and Arsenal out of the title race a year after the central England team’s priority was fighting relegation. Fourth-place Arsenal, who have gone 12 years without winning the league, were held 0-0 by Sunderland in yesterday’s other game. It was a valuable point for Sunderland, who climbed out of the relegation zone by going above Norwich on goal difference. “It is frustrating because we play to win the title,” Arsenal manager Arsene Wenger said. Arsenal’s season now rests on holding on to fourth place and qualifying for the Champions League, with Manchester United five points behind in fifth place. United also have an FA Cup final to look forward to. Louis van Gaal’s side discovered yesterday that they will face Crystal Palace on May 21 in a repeat of the 1990 final. In a semi-final overshadowed by Leicester’s game, Palace beat Watford 2-1 with all three goals coming from headers. Yannick Bolasie’s opener was cancelled out by Troy Deeney but Connor Wickham restored Palace’s lead. United also beat Everton 2-1 on Saturday. MAN CITY OUT LONDON (AP): No Jamie Vardy, no problem for Leicester. Even with their top-scorer suspended, the Premier League leaders still overpowered Swansea 4-0 yesterday to move another step closer to collecting the trophy. The only team which can now catch Leicester is Tottenham, but the preseason 5,000-1 outsiders have their destiny in their own hands. Tottenham are eight points behind Leicester in second place going into today’s game against West Bromwich Albion. Regardless of what Tottenham do in their last four games, Leicester will be guaranteed the top flight for the first time in its 132-year history by collecting five points from their remaining three fixtures. Leicester dismantled Swansea with their biggest win in three months. Vardy’s replacement, Leonardo Ulloa, scored twice after Riyad Mahrez’s opener and Marc Albrighton completed the rout. “I talked to my players before the match and I said we had a dream so far, now make a dream reality,” Leicester manager Claudio Ranieri said. “Now is the right moment to push. If Tottenham are better than us, OK, but we have to fight because we will never have this fantastic moment (again). “Now there are only three matches, we know they are very important for our history but for this reason we give everything. We play with our hearts and it’s difficult to beat those who play with the heart and soul.” The attacking threat provided without 22-goal Vardy will have reassured the Foxes they can cope without him for longer. The England striker is waiting to discover from the English Football Association if his one-match ban will be extended over the angry reaction to being sent off in last weekend’s draw against West Ham. “Without Jamie, everyone makes something more and it was a fantastic show to see my players fight and play together,” Ranieri said.

New Orleans Hornets coach Monty Williams was a serviceable player for the New York Knicks, a first-round pick out of Notre Dame who was smarter than he was talented. He lasted 10 years in the NBA on being hard-nosed and cerebral.His transition to coaching was surprising at first, but upon further review, made perfect sense. He understood the game. And what he has done since becoming coach of the New Orleans Hornets in his two year has earned him a four-year contract extension, the AP reported.“I would like to thank Mr. (Tom) Benson, his family, Mickey (Loomis, executive vice president) and Dell (Demps, general manager) for putting their trust in me and showing me their commitment,” Williams said in a statement released by the club. “The love and support the city and its fans have shown me and my family in the time we have been here has been incredible and I look forward to continuing to work to make the city and the Benson family proud of the Hornets.”Williams came to the Hornets after five seasons as the assistant coach in Portland under then-head coach Nate McMillan.“The Hornets have a promising future and an exciting young nucleus,” said Hornets executive vice president Mickey Loomis. “It is our opinion that Monty is the perfect coach to develop and lead this group of talent going forward.”Williams took the Hornets to the playoffs his first season with a 46-36 record. Last season, the club went 21-45 after trading star Chris Paul to the Los Angeles Clippers in a deal that helped New Orleans build for the future with the acquisition of 23-year-old shooting guard Eric Gordon and an additional first-round draft choice.The Hornets then won the NBA’s draft lottery and selected Kentucky star Anthony Davis first overall and added Duke’s Austin Rivers with the 10th pick.This off-season, the Hornets have also traded to acquire forward Ryan Anderson from Orlando and center Robin Lopez from Phoenix, giving Williams something to work with for the future.

The research team of Asst. Prof. Johnpierre Paglione faced significant challenges in designing and implementing an experiment to determine the relative importance of quantum criticality in the cuprates. “The relevance of quantum criticality to shaping the properties of the cuprates is a pivotal question that remains unsolved,” Paglione tells Phys.org. “There are several ‘phases’ of these materials, including insulating, anomalous metallic, superconducting and normal metallic ground states – and understanding how these phases arise, coexist, and interact will allow for understanding the underlying physics that gives rise to them.” This is, he adds, the key impetus motivating researchers to understand the phase diagram of the cuprates.“One of the main challenges in doing so,” Paglione continues, “lies in the fact that there are few actual compounds that can be tuned through the full phase diagram – that is, from parent compound Mott insulator, through the anomalous non-Fermi liquid metallic/superconducting phase, to over-doped ‘normal’ metal. Well-known compounds like yttrium barium copper oxide (YBCO) have a limited range of chemical tuning – by way of oxygen doping or rare earth substitution – which make it difficult to study their properties through all three of these regions of the phase diagram, resulting in the necessity to patch together results from different systems to obtain what is widely held to be the generic cuprate phase diagram.” Luckily, Paglione points out, there are some systems, such as the “hole-doped” (La,Sr)2CuO4 and “electron-doped” (La,Ce)2CuO4 that allow for a wide range of substitution – and ongoing work has made use of these to answer many questions.“Another challenge,” Paglione explains, “lies in understanding the details and importance of some of the anomalous normal state properties, that is, above the temperature where superconductivity exists. In particular, most studies to date have focused on the hole-doped cuprates because their superconducting phases exhibit the highest transition temperatures, but these systems all harbor the infamous ‘pseudogap’ phase (a state where the Fermi surface of a material possesses a partial gap) on the underdoped side of the superconducting phase. Much effort has been spent on understanding whether this phase is a ‘friend or foe’ of superconductivity.” (Phys.org) — Superconductivity is a complex phenomenon that is considerably more intricate than many casual observers realize. This caveat applies equally to the subset of this research known as high-temperature superconductivity – which, it should be noted, is described as such only in relation to the near absolute zero temperature range at which conventional superconductors are found, and furthermore is not to be confused with the loftier goal of room-temperature superconductivity. That said, certain aspects of electronic properties in high-temperature copper oxide, or cuprate, superconductors imply that the absence of conventional metallic Fermi liquid behavior – the standard model of electrons in metals – and the presence of unconventional superconductivity are closely related. While such a partnership often occurs proximate to what is known as a quantum critical point (a special class of continuous phase transition that takes place at the absolute zero of temperature in a material where the phase transition temperature has been driven to zero by the application of a pressure, field or through doping), the role of quantum criticality in the cuprates has remained elusive. Recently, however, researchers at the Center for Nanophysics and Advanced Materials and Department of Physics, University of Maryland, have studied the anomalous properties of the cuprate material La2-xCexCuO4, or LCCO, concluding that quantum criticality plays a significant role in shaping the anomalous properties of these superconductive materials. Copyright 2012 Phys.org All rights reserved. This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of PhysOrg.com. Another issue was that cuprate superconductivity is an amazing phase, having the highest transition temperatures and critical magnetic fields of any known material – but for the purposes of studying the underlying ground state that gives rise to Cooper pairing this is actually a key difficulty. ”Specifically,” Paglione notes, “to study the true ground state properties at the lowest energy scales – those approaching absolute zero – superconductivity must be somehow suppressed. Such high temperatures and fields make it extremely difficult to do high-sensitivity experiments in a practical manner.”Addressing these issues required no small amount of ingenuity, as well as the particular LCCO compound used in the study. “Firstly,” notes Paglione, “this compound is unique in that it can be synthesized with a wide range of cerium (Ce) concentrations that span across the entire phase diagram, from insulating (x=0) to overdoped metallic (x>0.175). Secondly, this is an electron-doped system, in which the anomalous pseudogap phase is absent. Therefore comparisons of its anomalous properties to those of its hole-doped counterparts with the pseudogap present has allowed us to identify traits common to both, and therefore not associated with the pseudogap phase.” This includes, most importantly, the linear-in-temperature normal state resistivity that surrounds the superconducting phase. “We can now associate this anomalous scattering with the presence of well-characterized magnetic fluctuations that are almost magnetically ordered, giving strong reinforcement to the well-known hypothesis of quantum critical fluctuations dominating the properties of the normal state,” Paglione explains.The lower transition temperatures and critical fields of this system allowed the team to probe the ground state in their lab using high but practically attainable extremes of temperature (0.020 Kelvin) and magnetic field (17 Tesla). “With this, we discovered a striking quantum critical scaling of the physical properties with the ratio of temperature to field, which is not seen in a normal metal due to an upper energy scale of the electron system – the Fermi energy – that dominates all characteristics of the metal, such that the normally static factor of temperature is now dynamic. This is a telltale sign of quantum criticality.”In addition, Paglione points out, there are other innovations that might be developed and applied to the current experimental design. “Due to the crystallographic nature of the LCCO system, it is only stable in thin-film form and therefore single-crystalline samples cannot be synthesized easily.” This is a drawback, since further study of the thermodynamic properties of the system – such as heat capacity and magnetization, which require more sample mass to detect – in the quantum critical regime would allow further insight into its physical description and origin. “Higher magnetic fields and even lower temperatures would allow us to extend the range of applicability of the anomalous properties and therefore further elucidate the extent to which standard model solid state physics fails to explain these materials,” says Paglione.Relatedly, the team has already defined the next steps to be applied to their research. “Currently we’re most interested in observing the same phenomena in other cuprate materials, allowing for more general conclusions to be made. In particular,” Paglione illustrates, “the similarities of the overdoped side of the phase diagram between hole- and electron-doped cuprates are striking, and they carry a strong potential statement about what governs the demise of superconductivity with increasing doping but require further verification in different compounds.”One particularly interesting outcome of the study is how the team’s findings impact the development of using the selective response of spin fluctuations and superconductivity to magnetic fields and charge doping to segregate the resulting two distinct signatures of criticality. “The observation of two distinct signatures of quantum criticality is an interesting find. We expected to see only one signature of critical magnetic fluctuations, as given by one set of critical exponents, since an incipient magnetic order and its strong quantum fluctuations are what most people believe lies ‘underneath the dome’ and drives the Cooper pairing. The observation of a second flavor of quantum fluctuations, which we conclude arises from the demise of the superconducting transition temperature to absolute zero, suggests that fluctuations of this separate type of order – that is, superconducting, not magnetic – can also cause anomalous physical properties to arise. These may in fact be the cause of most properties associated with the overdoped side of the phase diagram, including the suppression of superconductivity itself and the strong tuning of the eventual normal metal Fermi liquid ground state.” Paglione points out that a theory exists for this type of superconducting fluctuation, but a calculation of the expected transport properties has not been done. However, he adds that they are working with Prof. Galitski at the University of Maryland to do just this.Finally, Paglione explains, there are other research areas and applications that might benefit from their findings. “The study of quantum criticality is a wide field of research that overlaps with superconductivity in several areas, including the cuprates but also in heavy-fermion systems and the more recent discovery of superconductivity in iron-based materials. Our results have implications for all of these areas, where a strong interplay of superconductivity and magnetism results in an easily tunable phase diagram of the sort found in the cuprates. Beyond that,” he concludes, “a deeper understanding of high-temperature superconductivity in cuprates and iron-pnictides has the potential to allow for crystallographic engineering of new compounds that could harbor even higher superconducting transition temperatures useful for room temperature power, electronic and communications applications.” Explore further Swimming upstream: Flux flow reverses for lattice bosons in a magnetic field Journal information: Proceedings of the National Academy of Sciences More information: Quantum critical scaling at the edge of Fermi liquid stability in a cuprate superconductor, PNAS, Published online before print May 9, 2012, doi: 10.1073/pnas.1120273109 Doping evolution of magnetic field-temperature phase diagrams of La2-xCexCuO4.
