Symmetry-Enriched Criticality in a Coupled Spin-Ladder
Suman Mondal, Adhip Agarwala, Tapan Mishra +1
We study a one-dimensional ladder of two coupled XXZ spin chains and identify several distinct gapless symmetry-enriched critical phases. These have the same unbroken symmetries an…
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…
Flux induced re-entrant dynamics in the quantum walk of interacting bosons
Mrinal Kanti Giri, Biswajit Paul, Tapan Mishra
We study the QW of two interacting bosons on a two-leg ladder lattice in the presence of an artificial magnetic field. By considering an uniform flux piercing through the ladder, w…
