Su-Schrieffer-Heeger model driven by sequences of two unitaries: periodic, quasiperiodic, aperiodic, and random protocols
Maitri Ganguli, Diptiman Sen
We study the effect of driving the Su-Schrieffer-Heeger model using two unitary operators and in different combinations; the unitaries differ in the values of the inter…
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…
Emergent prethermal Bethe integrability in a periodically driven Rydberg chain
Saptadip Roy, Arnab Sen, Diptiman Sen +1
We study a chain of periodically driven Rydberg atoms and identify a class of drive protocols for which the system exhibits emergent prethermal Bethe integrability at special drive…
Floquet scars and prethermal fragmentation in a driven spin-one chain
Krishanu Ghosh, Diptiman Sen, K. Sengupta
We study the periodic dynamics of a spin-one chain driven using a square-pulse protocol with amplitude and frequency . The Hamiltonian of the spin chain hosts a thermod…
Heating suppression via two-rate random and quasiperiodic drive protocols
Krishanu Ghosh, Sayan Choudhury, Diptiman Sen +1
We study a random and quasiperiodically driven one-dimensional non-integrable PXP spin chain in a magnetic field for two distinct drive protocols. Each of these protocols involves…
Quantum dynamics of a spin model with an extensive degeneracy
Krishanu Ghosh, Diptiman Sen, K. Sengupta
We study the role played by extensive degeneracy in shaping the nature of the quantum dynamics of a one-dimensional spin model for both ramp and periodic drive protocols. The model…
