Diagnosing non-Hermitian Many-Body Localization and Quantum Chaos via Singular Value Decomposition
Federico Roccati, Federico Balducci, Ruth Shir +1
Strong local disorder in interacting quantum spin chains can turn delocalized eigenmodes into localized eigenstates, giving rise to many-body localized (MBL) phases. This is accomp…
Decomposing the Spectral Form Factor
Pablo Martinez-Azcona, Ruth Shir, Aurélia Chenu
Correlations between the energies of a system's spectrum are one of the defining features of quantum chaos. They can be probed using the Spectral Form Factor (SFF). We investigate…
Hermitian and Non-Hermitian Topology from Photon-Mediated Interactions
Federico Roccati, Miguel Bello, Zongping Gong +4
Light can mediate effective dipole-dipole interactions between atoms or quantum emitters coupled to a common environment. Exploiting them to tailor a desired effective Hamiltonian…
Stochastic Operator Variance: an observable to diagnose noise and scrambling
Pablo Martinez-Azcona, Aritra Kundu, Adolfo del Campo +1
Noise is ubiquitous in nature, so it is essential to characterize its effects. Considering a fluctuating Hamiltonian, we introduce an observable, the stochastic operator variance (…
