Quantum fluctuations can promote or inhibit glass formation
Quantum fluctuations can glass formation

The very nature of glass is somewhat mysterious: while relaxation times in glasses are of
sufficient magnitude that large-scale motion on the atomic level is essentially as slow as it is in the cryst...
Non-equilibrium fluctuations at the QCD phase transition
Non-equilibrium fluctuations QCD phase transition

We study the chiral phase transition by the non-equilibrium propagation of the sigma field. A quark fluid acts as a heat bath in local thermal equilibrium and evolves fluid dynamically.
Macroscopic quantum tunneling in multigap superconducting Josephson junctions: Escape rate enhancement via quantum fluctuations of Josephson-Leggett mode
Macroscopic quantum superconducting Josephson Escape rate enhancement Josephson-Leggett mode

We theoretically study the macroscopic quantum tunneling (MQT) in a hetero Josephson junction formed by a conventional single-gap superconductor and a multi-gap one such as ${MgB}_{2}$ and iron-based...

We study two broad classes of physically dissimilar problems, each corresponding to stochastically driven escape from a potential well. The first class, often used to model noise-induced order paramet...
