Markovian evolution of classical and quantum correlations in transverse-field XY model
Amit Kumar Pal, Indrani Bose
The transverse-field XY model in one dimension is a well-known spin model for which the ground state properties and excitation spectrum are known exactly. The model has an interest…

Transverse Ising Model: Markovian evolution of classical and quantum correlations under decoherence
Amit Kumar Pal, Indrani Bose
The transverse Ising Model (TIM) in one dimension is the simplest model which exhibits a quantum phase transition (QPT). Quantities related to quantum information theoretic measure…
