TL;DR: In this paper, the authors summarize some of the basic issues, including the extent to which the quantum criticality in heavy-fermion metals goes beyond the standard theory of order-parameter fluctuations, the nature of the Kondo effect in the quantum-critical regime, the non-Fermi-liquid phenomena that accompany quantum criticalities and the interplay between quantum criticalness and unconventional superconductivity.
Abstract: Quantum criticality describes the collective fluctuations of matter undergoing a second-order phase transition at zero temperature. Heavy-fermion metals have in recent years emerged as prototypical systems to study quantum critical points. There have been considerable efforts, both experimental and theoretical, that use these magnetic systems to address problems that are central to the broad understanding of strongly correlated quantum matter. Here, we summarize some of the basic issues, including the extent to which the quantum criticality in heavy-fermion metals goes beyond the standard theory of order-parameter fluctuations, the nature of the Kondo effect in the quantum-critical regime, the non-Fermi-liquid phenomena that accompany quantum criticality and the interplay between quantum criticality and unconventional superconductivity. At a zero-temperature phase transition from one ordered state to another, fluctuations between the two states lead to quantum critical behaviour that can lead to unexpected physics. Metals with ‘heavy’ electrons often harbour such weird states.

TL;DR: In this paper, a self-organized criticality model for dynamic systems is proposed, which states that many composite systems naturally evolve to a critical state in which a minor event starts a chain reaction that can affect any number of elements in the system.
Abstract: Just as the proverbial straw broke the camel's back, catastrophes, from earthquakes and avalanches to a stock market crash, can be triggered by a minor event The authors argue that complex systems naturally evolve to a critical state Their theory already has improved understanding of motion in the earth's crust, economies and ecosystems The theory of self-organized criticality states that many composite systems naturally evolve to a critical state in which a minor event starts a chain reaction that can affect any number of elements in the system Although composite systems produce more minor events than catastrophes, chain reactions of all sizes are an integral part of the dynamics According to the theory, the mechanism that leads to minor events is the same one that leads to major events Furthermore, composite systems never reach equilibrium but instead evolve from one metastable state to the next Self-organized criticality is a holistic theory: the global features, such as the relative number of large and small events, do not depend on the microscopic mechanisms Consequently, global features of the system cannot be understood by analyzing the parts separately To the authors' knowledge, self-organized criticality is the only model or mathematical description that hasmore » led to a holistic theory for dynamic systems« less

TL;DR: A new technique, based on fuzzy logic, for prioritizing failures for corrective actions in a Failure Mode, Effects and Criticality Analysis (FMECA), which allows the analyst to evaluate the risk associated with item failure modes directly using the linguistic terms that are employed in making the criticality assessment.
