Dynamical Signatures and Kibble-Zurek Scaling of Localization in Tilted Bose-Einstein Condensates
Argha Debnath, Radheshyam Saha, Ravindra W. Chhajlany +2
We study nonequilibrium signatures of tilt-induced localization in a one-dimensional Bose-Einstein condensate loaded in a shallow optical lattice. The tilt strength acts as a contr…

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…

Tilt-Induced Localization in Interacting Bose-Einstein Condensates for Quantum Sensing
Argha Debnath, Mariusz Gajda, Debraj Rakshit
We investigate localization transitions in interacting Bose-Einstein condensates (BECs) confined in tilted optical lattices, focusing on both the continuum limit accessed via shall…
