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…
