Berezinskii-Kosterlitz-Thouless transitions in classical and quantum long-range systems

G Giachetti, A Trombettoni, S Ruffo, N Defenu - Physical Review B, 2022 - APS
In the past decades, considerable efforts have been made to understand the critical features
of both classical and quantum long-range (LR) interacting models. The case of the …

Anharmonicity and quantum effects in thermal expansion of an Invar alloy

T Yokoyama, K Eguchi - Physical review letters, 2011 - APS
We have investigated the anharmonicity and quantum effects in the Invar alloy Fe 64.6 Ni

Quantum variance: a measure of quantum coherence and quantum correlations for many-body systems

I Frérot, T Roscilde - Physical Review B, 2016 - APS
Quantum coherence is a fundamental common trait of quantum phenomena, from the
interference of matter waves to quantum degeneracy of identical particles. Despite its …

Path-integral effective-potential method applied to extended x-ray-absorption fine-structure cumulants

T Yokoyama - Physical Review B, 1998 - APS
The path-integral effective-potential (EP) method was applied to the calculations of extended
x-ray-absorption fine-structure (EXAFS) cumulants. Temperature dependence of the EXAFS …

Learning interacting theories from data

C Merger, A René, K Fischer, P Bouss, S Nestler… - Physical Review X, 2023 - APS
One challenge of physics is to explain how collective properties arise from microscopic
interactions. Indeed, interactions form the building blocks of almost all physical theories and …
