Quantum Phase Transition in Dimerized Spin-1/2 Chains
Aparajita Das, Sreeparna Bhadra, Sonali Saha
Quantum phase transition in dimerized antiferromagnetic Heisenberg spin chain has been studied. A staircase structure in the variation of concurrence within strongly coupled pairs…
Model dependence of the multi-transonic behavior, stability properties and corresponding acoustic geometry for accretion onto a spinning black hole
Sonali Saha, Sharmistha Sen, Sankhasubhra Nag +2
Multi-transonic accretion for a spinning black hole has been compared among different disc geometries within post Newtonian pseudo potential framework. The variation of stationary…
Optical properties of perovskite alkaline earth titanates : a formulation
Kamal Krishna Saha, Tanusri Saha-Dasgupta, Abhijit Mookerjee +2
In this communication we suggest a formulation of the optical conductivity as a convolution of an energy resolved joint density of states and an energy-frequency labelled transitio…
