Emergent modular Luttinger liquid from spin-partitioned entanglement in the one-dimensional Hubbard model
Ãdám Bácsi, Catalin Pascu Moca, Balázs Dóra
We study the spin-partitioned entanglement Hamiltonian of the one-dimensional repulsive Hubbard model. By combining bosonization with exact diagonalization, we show that tracing ou…
Mimicry of chaos and -design in higher order OTOCs of Luttinger liquids
Balázs Dóra, Catalin Pascu Moca, Roderich Moessner
Out-of-time-order correlators (OTOCs) provide a fundamental metric for quantum chaos, but capturing the fine structure of information scrambling requires exploring their higher-ord…
Independent stabilizer Rényi entropy and entanglement fluctuations in random unitary circuits
Dominik Szombathy, Angelo Valli, CÄtÄlin PaÅcu 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…
Anomalous Quantum Relaxation in the Infinite Temperature Hubbard Chain
Catalin Pascu Moca, Balázs Dóra
The self-energy encodes the fundamental lifetime of quasiparticle excitations. In one dimension, it is known to display anomalous behavior at zero temperature for interacting fermi…
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…
Spectral Properties Versus Magic Generation in -doped Random Clifford Circuits
Dominik Szombathy, Angelo Valli, CÄtÄlin PaÅcu 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…
