Fidelity, Rosen-Zener Dynamics, Entropy and Decoherence in one dimensional hard-core bosonic systems
Sthitadhi Roy, Tanay Nag, Amit Dutta
We study the non-equilibrium dynamics of a one-dimensional system of hard core bosons (HCBs) in the presence of an onsite potential (with an alternating sign between the odd and ev…
Quenching Dynamics and Quantum Information
Tanay Nag, Amit Dutta, Ayoti Patra
We review recent studies on the measures of zero temperature quantum correlations namely, the quantum entanglement (concurrence) and discord present in the final state of a transve…
Quantum effects in classical chaos through intermittency
T. S. Nag, P. Banerjee
The semi-quantal dynamics is applied to investigate the influence of quantum fluctuations on problems in classical chaos through intermittency involving bifurcations. The results o…
The scaling of the decoherence factor of a qubit coupled to a spin chain driven across quantum critical points
Tanay Nag, Uma Divakaran, Amit Dutta
We study the scaling of the decoherence factor of a qubit (spin-1/2) using the central spin model in which the central spin (qubit) is globally coupled to a transverse XY spin chai…
