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…
Localized states and skin effect around non-Hermitian impurities in tight-binding models
Balázs Hetényi, Balázs Dóra
We use the generalized Bloch theorem formalism of Alase {\it et al.} [{\it Phys. Rev. Lett.} {\bf 117} 076804 (2016)] to analyze simple one-dimensional tight-binding lattice system…
Infinite temperature spin dynamics in the asymmetric Hatsugai-Kohmoto model
Ãdám Bácsi, Doru Sticlet, Catalin Pascu Moca +1
We focus on the infinite temperature dynamical spin structure factor of the asymmetric Hatsugai-Kohmoto model, the relative of the asymmetric Hubbard model. It is characterized by…
Dynamic scaling and Family-Vicsek universality in quantum spin chains
CÄtÄlin PaÅcu 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…
