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…

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…

Dynamics of Bright Soliton Under Cubic-Quartic Interactions in Quasi One-Dimensional Geometry

Argha Debnath, Ayan Khan, Prasanta K Panigrahi

Recent inspection of liquid-like state in ultracold atomic gases due to the stabilization mechanism through the delicate balance between effective mean-field and beyond mean-field…

Interaction of One-Dimensional Quantum Droplets with Potential Wells and Barriers

Argha Debnath, Ayan Khan, Boris Malomed

We address static and dynamical properties of one-dimensional (1D) quantum droplets (QDs) under the action of local potentials in the form of narrow wells and barriers. The QDs are…

Dropleton-Soliton Crossover mediated via Trap Modulation

Argha Debnath, Ayan Khan, Saurabh Basu

We report a droplet to a soliton crossover by tuning the external confinement potential in a dilute Bose-Eienstein condensate by numerically solving the modified Gross-Pitaevskii e…

Signature of Supersolidity in a Driven Cubic-Quartic Nonlinear Schrödinger Equation

Argha Debnath, Jammu Tarun, Ayan Khan

We present analytical solution, which is periodic in nature, for a driven cubic-quartic nonlinear Schrödinger equation (DCQNLSE) placed in a bi-chromatic optical lattice. The solut…

Investigation of Quantum Droplet: An Analytical Approach

Argha Debnath, Ayan Khan

Recent observations of droplets in dipolar and binary Bose-Einstein condensate (BEC) motivates us to study the theory of droplet formation in detail. Precisely, we are interested i…

On Solving Cubic-Quartic Nonlinear Schrödinger Equation in a Cnoidal Trap

Argha Debnath, Ayan Khan

The recent observations of quantum droplet in ultra-cold atomic gases have opened up new avenues of fundamental research. The competition between mean-field and beyond mean-field i…
