Quantifying non-Hermiticity using single- and many-particle quantum properties
Soumik Bandyopadhyay, Philipp Hauke, Sudipto Singha Roy
The non-Hermitian paradigm of quantum systems displays salient features drastically different from Hermitian counterparts. In this work, we focus on one such aspect, the difference…

Unveiling Eigenstate Thermalization for Non-Hermitian systems
Sudipto Singha Roy, Soumik Bandyopadhyay, Ricardo Costa de Almeida +1
The eigenstate thermalization hypothesis (ETH) has been highly influential in explaining thermodynamic behavior of closed quantum systems. As of yet, it is unclear whether and how…
