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 …

Relevance in the renormalization group and in information theory

A Gordon, A Banerjee, M Koch-Janusz, Z Ringel - Physical Review Letters, 2021 - APS
The analysis of complex physical systems hinges on the ability to extract the relevant

Neural information squeezer for causal emergence

J Zhang, K Liu - Entropy, 2022 - mdpi.com
Conventional studies of causal emergence have revealed that stronger causality can be
obtained on the macro-level than the micro-level of the same Markovian dynamical systems …

Superconducting fluctuations and charge-4 plaquette state at strong coupling

Q Qin, JJ Dong, Y Sheng, D Huang, Y Yang - Physical Review B, 2023 - APS
We apply the static auxiliary field Monte Carlo approach to study phase correlations of the
pairing fields in a model with spin-singlet pairing interaction. We find that the short-and long …

Symmetries and phase diagrams with real-space mutual information neural estimation

DE Gökmen, Z Ringel, SD Huber, M Koch-Janusz - Physical Review E, 2021 - APS
Real-space mutual information (RSMI) was shown to be an important quantity, formally and
from a numerical standpoint, in finding coarse-grained descriptions of physical systems. It …
