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…
Independent stabilizer Rényi entropy and entanglement fluctuations in random unitary circuits
Dominik Szombathy, Angelo Valli, Cătălin Paşcu Moca +2
We investigate numerically the joint distribution of magic () and entanglement () in -qubit Haar-random quantum states. The distribution as well as the marginal…
Spectral properties of fractionalized Shiba states
Cătălin Paşcu Moca, Csanád Hajdú, Balázs Dóra +1
A magnetic impurity in a BCS superconductor induces the formation of a Shiba state and drives a local quantum phase transition. We generalize this concept to a one-dimensional supe…
Underscreened Kondo Compensation in a Superconductor
Anand Manaparambil, Cătălin Paşcu Moca, Gergely Zaránd +1
A magnetic impurity with a larger spin remains partially screened by the Kondo effect when embedded in a metal. However, when placed within an -wave superconductor, the in…
Spectral Properties Versus Magic Generation in -doped Random Clifford Circuits
Dominik Szombathy, Angelo Valli, Cătălin Paşcu Moca +4
We study the emergence of complexity in deep random -qubit -gate doped Clifford circuits, as reflected in their spectral properties and in magic generation, characterized by…
Kondo Compensation in a Pseudogap Phase: a Renormalization Group Study
Csanád Hajdú, Cătălin Paşcu Moca, Balázs Dóra +2
We investigate the critical behavior of the Kondo compensation in the presence of a power-law pseudogap in the density of states, . For , this model exhi…
Efficient computation of cumulant evolution and full counting statistics: application to infinite temperature quantum spin chains
Angelo Valli, Cătălin Paşcu Moca, Miklós Antal Werner +4
We propose a numerical method to efficiently compute quantum generating functions (QGF) for a wide class of observables in one-dimensional quantum systems at high temperature. We o…
Quantum quenches in the sine--Gordon model: a semiclassical approach
Márton Kormos, Gergely Zaránd
We compute the time evolution of correlation functions after quantum quenches in the sine--Gordon model within the semiclassical approximation which is expected to yield accurate r…
