Imprints of information scrambling on eigenstates of a quantum chaotic system
Bikram Pain, Ratul Thakur, Sthitadhi Roy
How are the spatial and temporal patterns of information scrambling in locally interacting quantum many-body systems imprinted on the eigenstates of the system's time-evolution ope…

Logarithmic entanglement lightcone from eigenstate correlations in the many-body localised phase
Ratul Thakur, Bikram Pain, Sthitadhi Roy
We investigate the operator entanglement of the time-evolution operator through the framework of eigenstate correlations. Focusing on strongly disordered quantum many-body systems…
