Hellmann Feynman Theorem in Non-Hermitian system
Gaurav Hajong, Ranjan Modak, Bhabani Prasad Mandal
We revisit the celebrated Hellmann-Feynman theorem (HFT) in the PT invariant non-Hermitian quantum physics framework. We derive a modified version of HFT by changing the definition…

Engineering skin effect across a junction of Hermitian and non-Hermitian lattice
Ranjan Modak
We study a system where the two edges of a non-Hermitian lattice with asymmetric nearest-neighbor hopping are connected with two Hermitian lattices with symmetric nearest-neighbor…

Non-Hermitian description of sharp quantum resetting
Ranjan Modak, S. Aravinda
We study a non-interacting quantum particle, moving on a one-dimensional lattice, which is subjected to repetitive measurements. We investigate the consequence when such motion is…
