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…
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…
Engineering edge states in two-leg SSH ladder and their topoelectric circuit realization
Anish Kuanr, Rajashri Parida, Saralasrita Mohanty +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…
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-…
