We discuss one-loop radiative corrections to the sphaleron-induced baryon number-violating transition rate near the electroweak phase transition in the standard model. We emphasize that in the case of a first-order transition a rearrangement of the loop expansion is required close to the transition temperature. The corresponding expansion parameter, the effective 3-dimensional gauge coupling ap...

The critical temperature Tc of a superconductor/ferromagnet ~SF! bilayer can exhibit nonmonotonic dependence on the thickness d f of the F layer. SF systems have been studied for a long time; according to the experimental situation, a ‘‘dirty’’ limit is often considered which implies that the mean free path in the layers is the second smallest spatial scale after the Fermi wavelength. However, ...

Based on low-temperature experimental data in solid dielectric crystals, we derive a model of heat conduction for rigid materials using the theory of thermodynamic internal state variables. The model is intended to admit wavelike propagation of heat below—and diffusive conduction above—a particular temperature value A rapid decay of the speed of thermal waves occurs just below this temperature,...

The strongly correlated regime of the crossover from Bardeen-Cooper-Schrieffer pairing to Bose-Einstein condensation can be realized by diluting a system of two-component fermions with a short-range attractive interaction. We investigate this system via a novel continuous-space-time diagrammatic determinant Monte Carlo method and determine the universal curve Tc/epsilonF for the transition temp...
