Sunburst quantum Ising battery under periodic delta-kick charging
Ankita Mazumdar, Akash Mitra, Shashi C. L. Srivastava
Most quantum batteries studied so far with notable exception of Sachdev-Ye-Kitaev (SYK) batteries are based on integrable models, where superlinear scaling of charging power and he…

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…

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…
