Dipolar confinement-induced resonances of ultracold gases in waveguides

ORAL

Abstract

Exploring the impact of anisotropic dipolar interactions for ultracold collisions in quasi-one-dimensional traps we derive and analyze dipolar confinement-induced resonances (DCIRs) attributed to different angular momentum states. Our analysis is based on an extended $K$-matrix approach for quasi-one dimensional geometries. An analytically derived resonance condition allows us to predict the positions of DCIRs. The results obtained within the $K$-matrix theory are in excellent agreement with corresponding exact numerical calculations.
