Quantum resonance-enhanced performance of quantum battery
Ankita Mazumdar, Shashi C. L. Srivastava, Sanku Paul
Quantum resonance arising whenever the ratio of the intrinsic system frequency to the driving frequency becomes a rational number has been demonstrated to generate super-linear ent…
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…
Sunburst quantum Ising model under interaction quench: entanglement and role of initial state coherence
Akash Mitra, Shashi C. L. Srivastava
We study the non-equilibrium dynamics of an isolated bipartite quantum system, the sunburst quantum Ising model, under interaction quench. The pre-quench limit of this model is two…
Unbounded quantum backflow in two dimensions
Maximilien Barbier, Arseni Goussev, Shashi C. L. Srivastava
Quantum backflow refers to the counterintuitive fact that the probability can flow in the direction opposite to the momentum of a quantum particle. This phenomenon has been seen to…
