State-Selective Floquet Memory in Degenerate Manifolds
Ayan Sahoo, Argha Debnath, Debraj Rakshit
In order to understand which initial states retain memory under periodic driving, it is necessary to depart from the ideal limit giving rise to invariant structures and work inside…
Power-law-graded Ising Interactions Stabilize Time Crystals Realizing Quantum Energy Storage and Sensing
Ayan Sahoo, Debraj Rakshit
We study discrete time-crystalline (DTC) phases in one-dimensional spin-1/2 chains with power-law-graded Ising interactions under periodic Floquet driving. By generalizing Stark lo…
Quantum sensing with ultracold simulators in lattice and ensemble systems: a review
Keshav Das Agarwal, Sayan Mondal, Ayan Sahoo +3
Sensing of parameters is an important aspect in all disciplines, with applications ranging from fundamental science to medicine. Quantum sensing and metrology is an emerging field…
Enhanced sensing of a weak Stark field under the influence of Aubry-André-Harper criticality
Ayan Sahoo, Debraj Rakshit
The localization transition can be exploited as a resource for achieving quantum-enhanced sensitivity in parameter estimation. We demonstrate that by employing different classes of…
Multicritical quantum sensors driven by symmetry-breaking
Sayan Mondal, Ayan Sahoo, Ujjwal Sen +1
Quantum criticality has been demonstrated as a useful quantum resource for parameter estimation. This includes second-order, topological and localization transitions. In all these…
Stark localization near Aubry-André criticality
Ayan Sahoo, Aitijhya Saha, Debraj Rakshit
In this work, we investigate the Stark localization near the Aubry-André (AA) critical point. We perform careful studies for reporting system-dependent parameters, such as localiza…
Localization Driven Quantum Sensing
Ayan Sahoo, Utkarsh Mishra, Debraj Rakshit
We show that the delocalization-localization transition in a quantum-many body (QMB) systems is a compelling quantum resource for achieving quantum-enhanced sensitivity in paramete…
