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…
Non-equilibrium dynamics of superconductivity in the Hatsugai-Kohmoto model
Ãdám Bácsi, Balázs Dóra
We study the non-equilibrium dynamics of the superconducting order parameter in the Hatsugai-Kohmoto (HK) model. In the absence of superconductivity, its ground state is a non-Ferm…
Spectral properties of fractionalized Shiba states
CÄtÄlin PaÅcu 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…
Momentum space magic for the transverse field quantum Ising model
Balázs Dóra, CÄtÄlin PaÅcu Moca
Stabilizer entropies and quantum magic have been extensively explored in real-space formulations of quantum systems within the framework of resource theory. However, interesting an…
Kondo Compensation in a Pseudogap Phase: a Renormalization Group Study
Csanád Hajdú, CÄtÄlin PaÅcu 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…
