Optimization of collisional Feshbach cooling of an ultracold nondegenerate gas
Marlon Nuske, Eite Tiesinga, L. Mathey
We optimize a collision-induced cooling process for ultracold atoms in the nondegenerate regime. It makes use of a Feshbach resonance, instead of rf radiation in evaporative coolin…
Tunable Spin-Orbit Coupling via Strong Driving in Ultracold Atom Systems
K. Jiménez-García, L. J. LeBlanc, R. A. Williams +5
Spin-orbit coupling (SOC) is an essential ingredient in topological materials, conventional and quantum-gas based alike.~Engineered spin-orbit coupling in ultracold atom systems --…
Reactive collisions in confined geometries
Zbigniew Idziaszek, Krzysztof Jachymski, Paul S. Julienne
We consider low energy threshold reactive collisions of particles interacting via a van der Waals potential at long range in the presence of external confinement and give analytic…
2D Superexchange mediated magnetization dynamics in an optical lattice
R. C. Brown, R. Wyllie, S. B. Koller +3
The competition of magnetic exchange interactions and tunneling underlies many complex quantum phenomena observed in real materials. We study non-equilibrium magnetization dynamics…
Metastable Bose-Einstein Condensation in a Strongly Correlated Optical Lattice
David McKay, Ushnish Ray, Stefan Natu +3
We experimentally and theoretically study the peak fraction of a Bose-Einstein condensate loaded into a cubic optical lattice as the lattice potential depth and entropy per particl…

We theoretically establish the mean-field phase diagram of a homogeneous spin-, spin-orbit coupled Bose gas as a function of the spin-dependent interaction parameter, the Raman…
Position-dependent spin-orbit coupling for ultracold atoms

We theoretically explore atomic Bose-Einstein condensates (BECs) subject to position-dependent spin-orbit coupling (SOC). This SOC can be produced by cyclically laser coupling four…
Cold bosons in optical lattices: a tutorial for Exact Diagonalization
David Raventós, Tobias Graß, Maciej Lewenstein +1
Exact diagonalization techniques are a powerful method for studying many-body problems. Here, we apply this method to systems of few bosons in an optical lattice, and use it to dem…
Polar molecule reactive collisions in quasi-1D systems
Andrea Simoni, Srihari Srinivasan, Jean-Michel Launay +3
We study polar molecule scattering in quasi-one-dimensional geometries. Elastic and reactive collision rates are computed as a function of collision energy and electric dipole mome…

R. N. Bisset, R. M. Wilson, C. Ticknor
We demonstrate that measurements of number fluctuations within finite cells provide a direct means to study fluctuation scaling in a trapped two-component condensate. This quantum…
Realizing Exactly Solvable SU(N) Magnets with Thermal Atoms

We show that thermal fermionic alkaline-earth atoms in a flat-bottom trap allow one to robustly implement a spin model displaying two symmetries: the symmetry that permut…

We derive the ground-state energy for a small number of ultracold atoms in an isotropic harmonic trap using effective quantum field theory (EFT). Atoms are assumed to interact thro…
