Disorder driven Thouless charge pump in a quasiperiodic chain
Ashirbad Padhan, Tapan Mishra
Thouless charge pump enables a quantized transport of charge through an adiabatic evolution of the Hamiltonian exhibiting topological phase. While this charge pumping is known to b…
Re-entrant topological phase transition in a non-Hermitian quasiperiodic lattice
Ashirbad Padhan, Soumya Ranjan Padhi, Tapan Mishra
We predict a re-entrant topological transition in a one dimensional non-Hermitian quasiperiodic lattice. By considering a non-Hermitian generalized Aubry-André-Harper (AAH) model w…
Interacting bosons on a Su-Schrieffer-Heeger ladder: Topological phases and Thouless pumping
Ashirbad Padhan, Suman Mondal, Smitha Vishveshwara +1
We study the topological properties of hardcore bosons on a two-leg ladder consisting of two Su-Schrieffer-Heeger (SSH) chains that are coupled via hopping and interaction. We char…
Quantum phases of constrained bosons on a two-leg Bose-Hubbard ladder
Ashirbad Padhan, Rajashri Parida, Sayan Lahiri +2
Bosons in periodic potentials with very strong local interactions, known as the constrained bosons often exhibit interesting physical behavior. We investigate the ground state prop…
