Few-Body Physics in Spherical Shell Traps — •C. Moritz Carmesin1 and Maxim A.

With the recent progress in cold atom physics in microgravity [1–5] it is feasible to trap atoms in spherical shell-shaped traps. We start our analysis from exploring both bound and scattering states of two identical particles in spherical shell traps. Due to the non-separability of the center-of-mass and relative motions, we have solved the 6-dimensional Schrödinger equation numerically. Moreover, we have derived analytical models for the effective interaction between the particles for small and large shell radii, where the latter features quasi-two-dimensional dynamics in curved space.
