Majorana bound states in a hybrid Kitaev ladder with long-range pairing
Rajiv Kumar, Tapan Mishra, Levan Chotorlishvili +1
We investigate an inter-leg coupled hybrid Kitaev ladder composed of two parallel superconducting chains with distinct pairing interactions. The upper chain of the ladder hosts con…
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…
Tunable Floquet selection rules in a driven Ising chain
Rishi Paresh Joshi, Sanchayan Banerjee, Sneha Narasimha Moorthy +1
We study a periodically driven spin- Ising chain with a nearest-neighbour coupling and longitudinal field while a weak transverse field induces single-spin flips. Through Floq…
Emergent criticality in the Aubry-André model with periodic modulation
Sitaram Maity, Nilanjan Roy, Tapan Mishra
The Aubry-André model describes a system with quasiperiodic lattice modulation. In one dimension the AAH model is known to exhibit a sharp metal to insulator transition at a self-d…
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…
Engineering edge states in two-leg SSH ladder and their topoelectric circuit realization
Anish Kuanr, Rajashri Parida, Prabhu Prasad Tripathy +2
We study the topological phase transition in a two-leg Su-Schrieffer-Heeger (SSH) ladder by redefining the unit-cell structure. For both identical hopping dimerization pattern (uni…
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…
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…
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…
Floquet realization of prethermal Meissner phase in a two-leg flux ladder
Biswajit Paul, Tapan Mishra, K. Sengupta
We show that a periodically driven two-leg flux ladder hosting interacting hardcore bosons exhibits a prethermal Meissner phase for large drive amplitudes and at special drive freq…
Dynamics of interacting particles on a rhombus chain: Aharonov-Bohm caging and inverse Anderson transition
Sitaram Maity, Biswajit Paul, Soumya Prakash Sharma +1
The Aharonov-Bohm (AB) caging is the phenomenon of extreme localization of particles experiencing magnetic field in certain tight binding lattices. While the AB caging involves the…
Flux enhanced localization and reentrant delocalization in the quench dynamics of two interacting bosons on a Bose-Hubbard ladder
Mrinal Kanti Giri, Biswajit Paul, Tapan Mishra
We study the quench dynamics of two bosons possessing onsite repulsive interaction on a two-leg ladder and show that the presence of uniform flux piercing through the plaquettes of…
