Non-stabilizerness as a Diagnostic of Criticality and Exceptional Points in Non-Hermitian Spin Chains
Cătălin Paşcu Moca, Doru Sticlet, Balázs Dóra
We investigate non-stabilizerness, also known as ``magic,'' to understand criticality and exceptional points in non-Hermitian quantum many-body systems. Our focus is on parity-time…
Hot but Coherent: Doublons at Infinite Temperature in the Hubbard chain
Cătălin Paşcu Moca, Balázs Dóra, Gergely Zaránd
We investigate the spectral properties and the dynamics of doublons in the one-dimensional Hubbard model at infinite temperature. Using a Chebyshev expansion approach formulated in…
Quantum Coherence in a Maximally Hot Hubbard Chain
Cătălin Paşcu Moca, Ovidiu I. Patu, Balázs Dóra +1
We present a detailed study of the real-time dynamics and spectral properties of the one-dimensional fermionic Hubbard model at infinite temperature. Using tensor network simulatio…
Nonstabilizerness generation in a multiparticle quantum walk
Cătălin Paşcu 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 con…
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…
Dynamic scaling and Family-Vicsek universality in quantum spin chains
Cătălin Paşcu Moca, Balázs Dóra, Doru Sticlet +3
The Family-Vicsek scaling is a fundamental framework for understanding surface growth in non-equilibrium classical systems, providing a universal description of temporal surface ro…
