DOI: 10.1007/jhep10(2025)225

Abstract: This paper investigates the spectral form factor (SFF) of the quadratic R-para-particle Sachdev-Ye-Kitaev (R-PSYK2) model with various random matrix ensemble couplings. We generalize previous work on Gaussian Unitary Ensemble (GUE) couplings to all three Gaussian… read more here.

DOI: 10.1103/physreve.106.024208

Abstract: We study spectral form factor in periodically kicked bosonic chains. We consider a family of models where a Hamiltonian with the terms diagonal in the Fock space basis, including random chemical potentials and pairwise interactions,… read more here.

DOI: 10.1103/physreve.109.064208

Abstract: The spectral form factor (SFF) plays a crucial role in revealing the statistical properties of energy-level distributions in complex systems. It is one of the tools to diagnose quantum chaos and unravel the universal dynamics… read more here.

DOI: 10.1103/physrevlett.130.140403

Abstract: We show that non-Hermitian Ginibre random matrix behaviors emerge in spatially extended many-body quantum chaotic systems in the space direction, just as Hermitian random matrix behaviors emerge in chaotic systems in the time direction. Starting… read more here.
