Exotic superconductivity through bosons in a dynamical cluster approximation
(2015-08-07)
We study the instabilities towards (exotic) superconductivity of mixtures of spin-1/2 fermions coupled to scalar bosons on a two-dimensional square lattice with the Dynamical-Cluster-Approximation (DCA) using a numerically ...
Dynamical generation of spin squeezing in ultra-cold dipolar molecules
(2020-11-16)
We study a bulk fermionic dipolar molecular gas in the quantum degenerate regime confined in a two-dimensional geometry. Using two rotational states of the molecules we encode a spin 1/2 degree of freedom. To describe the ...
Population dynamics in Floquet realisation of Harper-Hofstadter Hamiltonian
(2015-04-21)
We study the recent Floquet-realisation of the Harper-Hofstadter model in a gas of cold bosonic atoms. We study in detail the scattering processes in this system in the weakly interacting regime due to the interplay of ...
Synthetic dimensions in the strong-coupling limit: supersolids and pair-superfluids
(2016-06-29)
We study the many-body phases of bosonic atoms with N internal states confined to a 1D optical lattice under the influence of a synthetic magnetic field and strong repulsive interactions. The N internal states of the atoms ...
Disentangling Pauli blocking of atomic decay from cooperative radiation and atomic motion in a 2D Fermi gas
(2021-08-05)
The observation of Pauli blocking of atomic spontaneous decay via direct measurements of the atomic population requires the use of long-lived atomic gases where quantum statistics, atom recoil and cooperative radiative ...
Scattering theory for Floquet-Bloch states
(2014-10-20)
Motivated by recent experimental implementations of artificial gauge fields for gases of cold atoms, we study the scattering properties of particles that are subjected to time-periodic Hamiltonians. Making use of Floquet ...
