Quantum Discord in a spin-1/2 transverse XY Chain Following a Quench
Tanay Nag, Ayoti Patra, Amit Dutta
We report a study on the zero-temperature quantum discord as a measure of two-spin correlation of a transverse XY spin chain following a quench across a quantum critical point and…

Path dependent scaling of geometric phase near a quantum multi-critical point
Ayoti Patra, Victor Mukherjee, Amit Dutta
We study the geometric phase of the ground state in a one-dimensional transverse XY spin chain in the vicinity of a quantum multi-critical point. We approach the multi-critical poi…
