Quantum criticality and universality in stationary state of long-range Kitaev model
Akash Mitra, Sanku Paul, Shashi C. L. Srivastava
We investigate the signature of quantum criticality in the long-time stationary state of the long-range Kitaev chain by performing various quench protocols. In this model, the pair…

Bound energy, entanglement and identifying critical points in 1D long-range Kitaev model
Akash Mitra, Shashi C. L. Srivastava
We investigate the entanglement structure of a bipartite quantum system through the lens of quantum thermodynamics in the absence of conformal symmetry. Specifically, we consider t…

Sunburst quantum Ising battery
Akash Mitra, Shashi C. L. Srivastava
We study the energy transfer process in the recently proposed sunburst quantum Ising model, which consists of two interacting integrable systems: a transverse Ising chain with a ve…
