Anomalous spectrum in a non-Hermitian quasiperiodic chain
Soumya Ranjan Padhi, Sanchayan Banerjee, Tanay Nag +1
The spectra of particles in disordered lattices can either be completely extended or localized or can be intermediate which hosts both the localized and extended states separated f…

Quasiperiodic and periodic extended Hatano-Nelson model: Anomalous complex-real transition and non-Hermitian skin effect
Soumya Ranjan Padhi, Ashirbad Padhan, Sanchayan Banerjee +1
We study the effect of quasiperiodic and periodic onsite potentials in a Hatano-Nelson model with next-nearest-neighbour hopping. By considering a non-reciprocal next-nearest-neigh…
