Nonequilibrium Evolution of Correlation Functions: A Canonical Approach
Supratim Sengupta, F. C. Khanna, Sang Pyo Kim
We study nonequilibrium evolution in a self-interacting quantum field theory invariant under space translation only by using a canonical approach based on the recently developed Li…
Stochastic Production Of Kink-Antikink Pairs In The Presence Of An Oscillating Background
Rajarshi Ray, Supratim Sengupta
We numerically investigate the production of kink-antikink pairs in a dimensional field theory subject to white noise and periodic driving. The twin effects of noise…
A Grand Canonical Ensemble Approach to the Thermodynamic Properties of the Nucleon in the Quark-Gluon Coupling Model
Hai Lin
In this paper, we put forward a way to study the nucleon's thermodynamic properties such as its temperature, entropy and so on, without inputting any free parameters by human hand,…
Multiple-Scale Analysis and Renormalization of Quenched Second Order Phase Transitions
Sang Pyo Kim, Supratim Sengupta, F. C. Khanna
A quenched second order phase transition is modeled by an effective -theory with a time-dependent Hamiltonian , whose symmetry is broken spontaneously in time. Th…
Resonant Production of Topological Defects
Sanatan Digal, Rajarshi Ray, Supratim Sengupta +1
We describe a novel phenomenon in which vortices are produced due to resonant oscillations of a scalar field which is driven by a periodically varying temperature T, with T remaini…
Electroweak Baryogenesis in a Cold Universe
Raghavan Rangarajan, Supratim Sengupta, Ajit M. Srivastava +1
We discuss the possibility of generating the baryon asymmetry of the Universe when the temperature of the Universe is much below the electroweak scale. In our model the evaporation…
