Magnetic field dependence of the entanglement entropy of one dimensional spin systems in quantum phase transition induced by a quench
Banasri Basu, Pratul Bandyopadhyay, Priyadarshi Majumdar
We study the magnetic field dependence of the entanglement entropy in quantum phase transition induced by a quench of the XX, XXX and the LMG model. The entropy for a block of …

Quantum Cournot equilibrium for the Hotelling-Smithies model of product choice
Ramij Rahaman, Priyadarshi Majumdar, B. Basu
This paper demonstrates the quantization of a spatial Cournot duopoly model with product choice, a two stage game focusing on non-cooperation in locations and quantities. With quan…

Density of defects and the scaling law of the entanglement entropy in quantum phase transition of one dimensional spin systems induced by a quench
Banasri Basu, Pratul Bandyopadhyay, Priyadarshi Majumdar
We have studied quantum phase transition induced by a quench in different one dimensional spin systems. Our analysis is based on the dynamical mechanism which envisages nonadiabati…
