Non-equilibrium dynamics of quantum systems: order parameter evolution, defect generation, and qubit transfer
Shreyoshi Mondal, Diptiman Sen, K. Sengupta
In this review, we study some aspects of the non-equilibrium dynamics of quantum systems. In particular, we consider the effect of varying a parameter in the Hamiltonian of a quant…
Quench dynamics and defect production in the Kitaev and extended Kitaev models
Shreyoshi Mondal, Diptiman Sen, K. Sengupta
We study quench dynamics and defect production in the Kitaev and the extended Kitaev models. For the Kitaev model in one dimension, we show that in the limit of slow quench rate, t…
Exact results for quench dynamics and defect production in a two-dimensional model
K. Sengupta, Diptiman Sen, Shreyoshi Mondal
We show that for a d-dimensional model in which a quench with a rate τ^{-1} takes the system across a d-m dimensional critical surface, the defect density scales as n \sim 1/τ^{mν/…
