Competing skin effect and quasiperiodic localization in the non-Hermitian Su-Schrieffer-Heeger chain: Reentrant delocalization, spectral topology destruction, and entanglement suppression
Souvik Ghosh
We investigate the interplay between the non-Hermitian skin effect and Aubry-André-Harper (AAH) quasiperiodic disorder in a one-dimensional Su-Schrieffer-Heeger (SSH) chain with n…

Reinterpreting Landauer conductance, solving the quantum measurement problem, grand unification
Kanchan Meena, Souvik Ghosh, P. Singha Deo
In a series of recent papers we have proved rigorously that time travel is a reality and very much feasible by using quantum mechanical processes. There are plenty of indirect expe…

Negative Local Partial Density of States
Kanchan Meena, Souvik Ghosh, P. Singha Deo
Real quantum systems can exhibit a local object called local partial density of states (LPDOS) that cannot be proved within the axiomatic approach of quantum mechanics. We demonstr…
