Emergence of a molecular quantum liquid in one dimension
Rajashri Parida, Biswajit Paul, Harish S. Adsule +4
We investigate the fate of a one-dimensional lattice superfluid formed by hard-core bosons, aka `atoms' (alternatively, a free spinless Fermi sea) subjected to nearest-neighbor att…
Floquet-induced suppression of thermalization in a quasiperiodic Ising chain
Biswajit Paul, Nilanjan Roy, Tapan Mishra
Many-body localized (MBL) systems are known to thermalize in periodically driven systems. In this work, we demonstrate that under proper driving protocol, this thermalization this…
Coupling induced emergent topology in a two-leg fermionic ladder
Rajashri Parida, Biswajit Paul, Soumya Ranjan Padhi +1
We investigate the ground state properties of spinless fermions on a two leg ladder, by allowing the nearest-neighbour hopping dimerization in one leg and uniform hopping in the ot…
Non-Hermitian comb effect in coupled clean and quasiperiodic chains
Soumya Ranjan Padhi, Souvik Roy, Biswajit Paul +2
We study localization properties in a system of non-Hermitian quasiperiodic chain coupled to a uniform chain or clean chain by inter-chain hopping. We find that in the limit of wea…
Anomalous slow-down of the bound state dynamics in a non-locally coupled quantum circuit
Biswajit Paul, Suman Mondal, Tapan Mishra
Additional hopping channels in a tight-binding lattice is known to introduce faster dynamics of a quantum mechanical particle. However, we show that in the case of a repulsively bo…
Realizing non-trivial doublon formation using a quantum computer
Biswajit Paul, Tapan Mishra
Dynamical formation of doublons or onsite repulsively bound pairs of particles on a lattice is a highly non-trivial phenomenon. In this work, we show the signatures of doublon form…
