Phases and phase transitions in a dimerized spin- XXZ chain
Harsh Nigam, Ashirbad Padhan, Diptiman Sen +2
We revisit the phase diagram of the dimerized XXZ spin- chain with nearest-neighbor couplings which was studied numerically in Phys. Rev. B 106, L201106 (2022). The mo…
Interaction driven topological phase transitions of hardcore bosons on a two-leg ladder
Rajashri Parida, Ashirbad Padhan, Tapan Mishra
We investigate the topological properties of hardcore bosons possessing nearest-neighbor repulsive interactions on a two-leg ladder. We show that by allowing nearest neighbour dime…
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…
