Abstract

In this project we will study the physical observables in weakly-bound few-atom systems in atomic traps. We will explore the mean-square radii and the binding energies of these systems in two dimensions and how they change as we continuously change the dimensionality of the system: in this case we will see the dimensional transition from 3-2-1 dimensions.
