Quantum critical phenomena

Physical Review B, 1976
This paper proposes an approach to the study of critical phenomena in quantum-mechanical systems at zero or low temperatures, where classical free-energy functionals of the Landau-Ginzburg-Wilson sort are not valid. The functional integral transformations first proposed by Stratonovich and Hubbard allow one to construct a quantum-mechanical ...

Theory of dynamic critical phenomena

Physics today, 1977
An introductory review of the central ideas in the modern theory of dynamic critical phenomena is followed by a more detailed account of recent developments in the field.

Quantum Field Theory and Critical Phenomena

, 2002
Introduced as a quantum extension of Maxwell's classical theory, quantum electrodynamic (QED) has been the first example of a quantum field theory (QFT).

Magnetism from conductors and enhanced nonlinear phenomena

, 1999
We show that microstructures built from nonmagnetic conducting sheets exhibit an effective magnetic permeability /spl mu//sub eff/, which can be tuned to values not accessible in naturally occurring materials, including large imaginary components of /spl

Hyperuniversality in quantum critical phenomena

Physical Review B, 1991
On applique les generalisations de l'universalite du facteur a deux echelles, ou l'hyperuniversalite, aux transitions de phases quantiques a la temperature zero. On trouve de nouvelles combinaisons des amplitudes universelles impliquant la densite superfluide dans les systemes de Bose bi- et tri-dimensionnels; on confirme et etend les propositions ...
