Long-range resonances in quasiperiodic many-body localization
Ashirbad Padhan, Jeanne Colbois, Fabien Alet +1
We investigate long-range resonances in quasiperiodic many-body localized (MBL) systems. Focusing on the Heisenberg chain in a deterministic Aubry-André potential, we complement s…
Topological phases of bosons with local parity coupling on a dimerized lattice
Ashirbad Padhan, Harsh Nigam
Symmetry-protected topological (SPT) phases in interacting bosonic systems have been widely explored, with many realizations emerging from the interplay of interactions, lattice ge…
Correlated hopping induced topological order in an atomic mixture
Ashirbad Padhan, Luca Barbiero, Tapan Mishra
The large majority of topological phases in one dimensional many-body systems are known to inherit from the corresponding single-particle Hamiltonian. In this work, we go beyond th…
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…
