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…

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 st…

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…
