Upper bounds on charging power and tangible advantage in quantum batteries
Sreeram PG, J. Bharathi Kannan, M. S. Santhanam
Quantum battery is expected to outperform its classical counterpart due to quantum effects. Usually, in a quantum battery made of cells, quantum advantage is demonstrated throu…
Dependence of Krylov complexity on the initial operator and state
Sreeram PG, J. Bharathi Kannan, Ranjan Modak +1
Krylov complexity, a quantum complexity measure which uniquely characterizes the spread of a quantum state or an operator, has recently been studied in the context of quantum chaos…
Probing the localization effects in Krylov basis
J. Bharathi Kannan, Sreeram PG, Sanku Paul +2
Krylov complexity (K-complexity) is a measure of quantum state complexity that minimizes wavefunction spreading across all the possible bases. It serves as a key indicator of opera…
Dichotomy in the effect of chaos on ergotropy
Sreeram PG, J. Bharathi Kannan, S. Harshini Tekur +1
The maximum unitarily extractable work from a quantum system -- ergotropy -- is the basic principle behind quantum batteries, a rapidly emerging field. This work studies ergotropy…
Asymmetric dynamical localization and precision measurement of BEC micromotion
S. Sagar Maurya, J. Bharathi Kannan, Kushal Patel +4
We employ a Bose Einstein Condensate (BEC) based atom-optic kicked rotor to generate an asymmetrically localized momentum distribution that depends upon initial velocity of the BEC…
Faster entanglement driven by quantum resonance in many-body kicked rotors
Sanku Paul, J. Bharathi Kannan, M. S. Santhanam
Quantum resonance in the paradigmatic kicked rotor system is a purely quantum effect that ignores the state of underlying classical chaos. In this work, it is shown that quantum re…
