Information scrambling in all-to-all interacting models
Abhik Kumar Saha, Tanay Pathak, Masaki Tezuka
Information scrambling is a hallmark of quantum chaos and thermalization in isolated quantum many-body systems. We investigate scrambling dynamics in the all-to-all interacting spi…
Entanglement production in the Sachdev-Ye-Kitaev Model and its variants
Tanay Pathak, Masaki Tezuka
Understanding how quantum chaotic systems generate entanglement can provide insight into their microscopic chaotic dynamics and can help distinguish between different classes of ch…
Extreme value statistics and eigenstate thermalization in kicked quantum chaotic spin- chains
Tanay Pathak, Masaki Tezuka
It is often expected (and assumed) for a quantum chaotic system that the presence of correlated eigenvalues implies that all the other properties as dictated by random matrix theor…
Probing quantum chaos through singular-value correlations in sparse non-Hermitian SYK model
Pratik Nandy, Tanay Pathak, Masaki Tezuka
Utilizing singular value decomposition, our investigation focuses on the spectrum of the singular values within a sparse non-Hermitian Sachdev-Ye-Kitaev (SYK) model. Unlike the com…
