Floquet engineering of edge states in the presence of staggered potential and interactions
Samudra Sur, Diptiman Sen
We study the effects of a periodically driven electric field applied to a variety of tight-binding models in one dimension. We first consider a non-interacting system with or witho…
Bilayer Haldane system: Topological characterization and adiabatic passages connecting Chern phases
Sourav Bhattacharjee, Souvik Bandyopadhyay, Diptiman Sen +1
We present a complete topological characterization of a bilayer composite of two Chern insulators (specifically, Haldane models) and explicitly establish the bulk-boundary correspo…
One-dimensional spin-orbit coupled Dirac system with extended -wave superconductivity: Majorana modes and Josephson effects
Adithi Udupa, Abhishek Banerjee, K. Sengupta +1
Motivated by the spin-momentum locking of electrons at the boundaries of topological insulators, we study a one-dimensional system of spin-orbit coupled massless Dirac electrons wi…
Dynamics of the vacuum state in a periodically driven Rydberg chain
Bhaskar Mukherjee, Arnab Sen, Diptiman Sen +1
We study the dynamics of the periodically driven Rydberg chain starting from the state with zero Rydberg excitations (vacuum state denoted by ) using a square pulse prot…
Thermodynamic behavior of modified integer-spin Kitaev models on the honeycomb lattice
Owen Bradley, Jaan Oitmaa, Diptiman Sen +1
We study the thermodynamic properties of modified spin- Kitaev models introduced by Baskaran, Sen and Shankar (Phys. Rev. B 78, 115116 (2008)). These models have the property th…
Restoring coherence via aperiodic drives in a many-body quantum system
Bhaskar Mukherjee, Arnab Sen, Diptiman Sen +1
We study the unitary dynamics of randomly or quasi-periodically driven tilted Bose-Hubbard (tBH) model in one dimension deep inside its Mott phase starting from a sy…
