A study of excess energy and decoherence factor of a qubit coupled to a one dimensional periodically driven spin chain
Tanay Nag
We take a central spin model (CSM), consisting of a one dimensional environmental Ising spin chain and a single qubit connected globally to all the spins of the environment, to stu…

Dynamics of decoherence: universal scaling of the decoherence factor
Sei Suzuki, Tanay Nag, Amit Dutta
We study the time dependence of the decoherence factor (DF) of a qubit globally coupled to an environmental spin system (ESS) which is driven across the quantum critical point (QCP…

Maximum group velocity in a one-dimensional model with a sinusoidally varying staggered potential
Tanay Nag, Diptiman Sen, Amit Dutta
We use Floquet theory to study the maximum value of the stroboscopic group velocity in a one-dimensional tight-binding model subjected to an on-site staggered potential varying sin…
