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…

Localization from Infinitesimal Kinetic Grading: Finite-size Scaling, Kibble-Zurek Dynamics and Applications in Sensing
Argha Debnath, Ayan Sahoo, Debraj Rakshit
We study a one-dimensional lattice model with site-dependent nearest-neighbor hopping amplitudes that follow a power-law profile. The hopping variation is controlled by a grading e…

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…
