Confinement-induced resonances for the creation of quasi-one-dimensional ultra cold gases of alkali--alkaline-earth dimers
Lorenzo Oghittu, Premjith Thekkeppatt, Nirav P. Mehta +4
We theoretically investigate the role of confinement-induced resonances (CIRs) in low-dimensional ultracold atomic mixtures for the formation of weakly bound dimers. To this end, w…
Lattice model parameters for ultracold nonreactive molecules: chaotic scattering and its limitations
Michael L. Wall, Rick Mukherjee, Shah Saad Alam +2
We calculate the parameters of the recently-derived many-channel Hubbard model that is predicted to describe ultracold nonreactive molecules in an optical lattice, going beyond the…
Microscopic derivation of multi-channel Hubbard models for ultracold nonreactive molecules in an optical lattice
Michael L. Wall, Nirav P. Mehta, Rick Mukherjee +2
Recent experimental advances in the cooling and manipulation of bialkali dimer molecules have enabled the production of gases of ultracold molecules that are not chemically reactiv…
Few-Boson Processes in the Presence of an Attractive Impurity under One-Dimensional Confinement
Nirav P. Mehta, Connor D. Morehead
We consider a few-boson system confined to one dimension with a single distinguishable particle of lesser mass. All particle interactions are modeled with -functions, but due to…
A variational approach to repulsively interacting three-fermion systems in a one-dimensional harmonic trap
N. J. S. Loft, A. S. Dehkharghani, N. P. Mehta +2
We study a three-body system with zero-range interactions in a one-dimensional harmonic trap. The system consists of two spin-polarized fermions and a third particle which is disti…
Born-Oppenheimer study of two-component few-particle systems under one-dimensional confinement
Nirav P. Mehta
The energy spectrum, atom-dimer scattering length, and atom-trimer scattering length for systems of three and four ultracold atoms with -function interactions in one dimension a…
