Periodic dynamics of population-imbalanced fermionic condensates in optical lattices

Avinaba Mukherjee, Raka Dasgupta

We investigate the dynamics of a population-imbalanced two-species fermionic system trapped in an optical lattice. The paired fermions here can form bosonic molecules via Feshbach…

Cold Atom Quantum Simulator for String and Hadron Dynamics in Non-Abelian Lattice Gauge Theory

Raka Dasgupta, Indrakshi Raychowdhury

We propose an analog quantum simulator for simulating real time dynamics of -d non-Abelian gauge theory well within the existing capacity of ultracold atom experiments. The…

Nonlinear Phenomena of Ultracold Atomic Gases in Optical Lattices: Emergence of Novel Features in Extended States

Gentaro Watanabe, B. Prasanna Venkatesh, Raka Dasgupta

The system of a cold atomic gas in an optical lattice is governed by two factors: nonlinearity originating from the interparticle interaction, and the periodicity of the system set…

Attraction-induced dynamical stability of a Bose-Einstein condensate in a nonlinear lattice

Raka Dasgupta, B. Prasanna Venkatesh, Gentaro Watanabe

We study multiple-period Bloch states of a Bose-Einstein condensate with spatially periodic interactomic interaction. Solving the Gross-Pitaevskii equation for the continuum model,…

Periodic dynamics of fermionic superfluids in the BCS regime

Analabha Roy, Raka Dasgupta, Sanhita Modak +2

We study the zero temperature non-equilibrium dynamics of a fermionic superfluid in the BCS limit and in the presence of a drive leading to a time dependent chemical potential $μ(t…

Effects of three-body scattering processes on BCS-BEC crossover

Raka Dasgupta

We investigate the BCS-BEC crossover taking into account an additional three-body interaction, which is essentially the scattering between the Cooper pairs and the newly formed bos…

Exotic Pairing Structures in Population-Imbalanced Fermionic Systems: Dynamics as a Probe

Raka Dasgupta, J. K. Bhattacharjee

We investigate a population-imbalanced two-species fermionic system where the resonantly-paired fermions combine to form bosonic molecules via Feshbach interaction. We study the dy…

Stability of the Breached Pair State for a Two-species Fermionic System in the Presence of Feshbach Resonance

Raka Dasgupta

We investigate the phenomenon of fermionic pairing with mismatched Fermi surfaces in a two-species system in the presence of Feshbach resonance, where the resonantly-paired fermion…
