Activated dynamics in the quantum random field Ising model
Ivan Balog, Lovro Šaravanja, Andrei A. Fedorenko
We study the critical dynamics of the quantum random-field Ising model using the nonperturbative functional renormalization group (NP-FRG). The static critical behavior is found to…

Constraint correlation functions of the one-dimensional Ising model in the scaling limit
Ivan Balog, Adam Rançon
We study the correlation function of the one-dimensional Ising model at fixed magnetization. Focusing on the scaling limit close to the zero-temperature fixed point, we show that t…

Universal and non-universal large deviations in critical systems
Ivan Balog, Bertrand Delamotte, Adam Rançon
Rare events play a crucial role in understanding complex systems. Characterizing and analyzing them in scale-invariant situations is challenging due to strong correlations. In this…
