Ultracold collisions of a neutral atom with a trapped ion in 1D
Seth T. Rittenhouse, Lorenzo Oghittu, Arghavan Safavi-Naini +2
We present a fully quantum mechanical description of a free Li atom scattering from a trapped Yb ion in one dimension. By reformulating the system in polar coordina…
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…
Homonuclear ultracold elastic -wave collisions of alkali atoms via multichannel quantum defect theory
Alyson Laskowski, Nirav Mehta
Multichannel quantum defect theory (MQDT) provides a powerful toolkit for describing and understanding collisions of cold alkali atoms. Various MQDT approximations differ primarily…
Scattering of two particles in a 1D lattice
Seth T. Rittenhouse, P. Giannakeas, Nirav P. Mehta
This study concerns the two-body scattering of particles in a one-dimensional periodic potential. A convenient ansatz allows for the separation of center-of-mass and relative motio…
Complex collisions of ultracold molecules: a toy model
Jia K. Yao, Nirav P. Mehta, Kaden R. A. Hazzard
We introduce a model to study the collisions of two ultracold diatomic molecules in one dimension interacting via pairwise potentials. We present results for this system, and argue…
A Model for Scattering with Proliferating Resonances: Many Coupled Square Wells
Nirav P. Mehta, Kaden R. A. Hazzard, Christopher Ticknor
We present a multichannel model for elastic interactions, comprised of an arbitrary number of coupled finite square-well potentials, and derive semi-analytic solutions for its scat…
