Dynamic scaling and Family-Vicsek universality in the Hubbard model at infinite temperature
CÄtÄlin PaÅcu Moca, Doru Sticlet, Balázs Dóra
We study Family-Vicsek scaling of charge, spin, and energy fluctuations in the one-dimensional Hubbard model at infinite temperature. Using a quantum generating function approach,…
Dynamical correlations in a dissipative XXZ spin chain
CÄtÄlin PaÅcu Moca, Doru Sticlet, Ovidiu I. Pâţu +1
We study dynamical spin correlations in a dissipative XXZ spin chain subject to uniform local spin-loss and pumping. Starting from a mixed steady state that is featureless albeit p…
Interaction-induced asymmetry in infinite-temperature dynamical correlations of hard-core anyons
Doru Sticlet, Ovidiu I. Pâţu, Ovidiu I. Pâţu +4
We study dynamical correlations of interacting hard-core anyons on a one-dimensional lattice at infinite temperature. This is a setting in which the many-body spectrum is independe…
Two-parameter Family-Vicsek scaling in a dissipative XXZ spin chain
CÄtÄlin PaÅcu Moca, Doru Sticlet, Tamás Vicsek +1
Family-Vicsek (FV) scaling provides an understanding for the growth and finite-size saturation of fluctuations in classical systems. Here, we extend the FV roughness to transferred…
Nonstabilizerness generation in a multiparticle quantum walk
CÄtÄlin PaÅcu Moca, Doru Sticlet, Balázs Dóra +3
We investigate the generation of non-stabilizerness, or magic, in a multi-particle quantum walk by analyzing the time evolution of the stabilizer Rényi entropy . Our study co…
Nonstabilizerness in open XXZ spin chains: Universal scaling and dynamics
Doru Sticlet, Balázs Dóra, Dominik Szombathy +2
Magic, or nonstabilizerness, is a crucial quantum resource, yet its dynamics in open quantum systems remain largely unexplored. We investigate magic in the open XXZ spin chain unde…
