Competing few-body correlations in ultracold Fermi polarons
AAPPS BulletinPolaron, a typical quasi-particle that describes a single impurity dressed with surrounding environment, serves as an ideal platform for bridging few- and many-body physics.

Expansion Dynamics of Rydberg-Dressed Ultracold Fermi Gas
PhotonicsWe present a theoretical investigation into the expansion dynamics of Rydberg-dressed ultracold Fermi gases. The effective interaction potential induced by Rydberg dressing significantly modifies the intrinsic properties and dynamical behavior of the ...

Universality of weakly bound dimers and Efimov trimers close to Li–Cs Feshbach resonances
New Journal of Physics, 2015 We study the interspecies scattering properties of ultracold Li–Cs mixtures in their two energetically lowest spin channels in the magnetic field range between 800 and 1000 G. Close to two broad Feshbach resonances (FR) we create weakly bound LiCs dimers

Cooper Pairs in 2D Trapped Atoms Interacting Through Finite-Range Potentials
AtomsThis work deals with the key constituent behind the existence of superfluid states in ultracold fermionic gases confined in a harmonic trap in 2D, namely, the formation of Cooper pairs in the presence of a Fermi sea in inhomogeneous confinement.

Dipole–dipole interactions in optical lattices do not follow an inverse cube power law
New Journal of Physics, 2013 We study the effective dipole–dipole interactions in ultracold quantum gases on optical lattices as a function of asymmetry in confinement along the principal axes of the lattice.

Physical Review X, 2019 Understanding the material parameters that control the superconducting transition temperature T_{c} is a problem of fundamental importance. In many novel superconductors phase fluctuations determine T_{c}, rather than the collapse of the pairing ...

Quantum vortex dipole as a probe of the normal component distribution
New Journal of PhysicsWe investigate the dynamics of quantum vortex dipoles in a strongly interacting, spin-imbalanced Fermi superfluid at zero temperature. Using fully microscopic time-dependent density functional theory, we demonstrate that the dipole trajectory is strongly

New Journal of Physics, 2015 We directly measured the normalized s -wave scattering cross-section of ultracold ^40 K atoms across a magnetic-field Feshbach resonance by colliding pairs of degenerate Fermi gases (DFGs) and imaging the scattered atoms.
