Quasi-localization dynamics in a Fibonacci quantum rotor
Sourav Bhattacharjee, Souvik Bandyopadhyay, Amit Dutta
We analyze the dynamics of a quantum kicked rotor (QKR) driven with a binary Fibonacci sequence of two distinct drive amplitudes. While the dynamics at low drive frequencies is fou…
Quantum magnetometry using two-stroke thermal machines
Sourav Bhattacharjee, Utso Bhattacharya, Wolfgang Niedenzu +2
The precise estimation of small parameters is a challenging problem in quantum metrology. Here, we introduce a protocol for accurately measuring weak magnetic fields using a two-le…
Asymptotic work statistics of periodically driven Ising chains
Angelo Russomanno, Shraddha Sharma, Amit Dutta +1
We study the work statistics of a periodically-driven integrable closed quantum system, addressing in particular the role played by the presence of a quantum critical point. Taking…
Loschmidt echo and dynamical fidelity in periodically driven quantum systems
Shraddha Sharma, Angelo Russomanno, Giuseppe E. Santoro +1
We study the dynamical fidelity and the Loschmidt echo , following a periodic driving of the transverse magnetic field of a quantum Ising chain (…
Quenching Dynamics and Quantum Information
Tanay Nag, Amit Dutta, Ayoti Patra
We review recent studies on the measures of zero temperature quantum correlations namely, the quantum entanglement (concurrence) and discord present in the final state of a transve…
