Kardar-Parisi-Zhang scaling in the Hubbard model
Cătălin Paşcu Moca, Miklós Antal Werner, Angelo Valli, Tomaž Prosen, Gergely Zaránd
Izvirni znanstveni članek
Oznake: fizika kondenzirane snovi;Hubbardov model;condensed matter physics;Hubbard model;
We explore the Kardar-Parisi-Zhang (KPZ) scaling in the one-dimensional Hubbard model, which exhibits global $SU_c(2) \otimes SU_s (2)$ symmetry at half filling, for the pseudocharge and the total spin. We analyze dynamical scaling properties of high-temperature charge and spin correlations and tran ...

Information propagation in the one-dimensional infinite temperature Hubbard model with a dissipative particle sink at the end of a semi-infinite chain is studied. In the strongly interacting limit, the two-site mutual information and the operator entanglement entropy exhibit a rich structure with tw ...

Efficient computation of cumulant evolution and full counting statistics: application to infinite temperature quantum spin chains
Angelo Valli, Cătălin Paşcu Moca, Miklós Antal Werner, Márton Kormos, Žiga Krajnik, Tomaž Prosen, Gergely Zaránd
Izvirni znanstveni članek
Oznake: kvantna statistična mehanika;kvantne spinske verige;quantum statistical mechanics;quantum spin chains;
We propose a numerical method to efficiently compute quantum generating functions for a wide class of observables in one-dimensional quantum systems at high temperature. We obtain high-accuracy estimates for the cumulants and reconstruct full counting statistics from the quantum generating functions ...
