Two dimensional dipolar scattering with a tilt

TL;DR

This paper investigates how tilting the polarization axis affects two-dimensional dipolar scattering, revealing angle-dependent resonances and bound state properties that enable tunable interactions.

Contribution

It introduces a controllable method to study anisotropic dipolar interactions in 2D by varying the polarization angle, highlighting the emergence of resonances and bound state behaviors.

Findings

Resonances occur as a function of polarization angle.

Scattering properties vary strongly with tilt angle.

Bound state characteristics depend on the polarization orientation.

Abstract

We study two body dipolar scattering in two dimensions with a tilted polarization axis. This tilt reintroduces the anisotropic interaction in a controllable manner. As a function of this polarization angle we present the scattering results in both the threshold and semi-classical regimes. We find a series of resonances as a function of the angle which allows the scattering to be tuned. However the character of the resonances varies strongly as a function angle. Additionally we study the properties of the molecular bound states as a function of the polarization angle.
