Energy spectrum of two atoms interacting via a short-range potential in higher partial waves

Abstract

<p>We study a two-atom system interacting via a short-range potential, and trapped by an optical lattice, in higher partial waves. These atoms may be made to interact strongly near a Feshbach resonance. Our main purpose is to find the relation between energy levels of the system and the scattering parameters in higher partial waves. We check our analytical results by numerical calculations and find the conditions under which this method is applicable for the d-wave.</p>
