Description

Over the last several years there has been a substantial increase of interest in artificial gauge fields and spin-orbit coupling for electrically neutral atoms [1–3]. The spin-orbit coupling with equal Rashba and Dresselhaus contributions has been recently implemented experimentally [4]. Here we consider manifestations of such a spin-orbit coupling for scattering of atoms at the impurity sites [5]. In particular, we show that the spin-orbit coupling can lead to both suppression or enhancement of the atomic backward scattering. Another topic to be discussed is creation of the artificial magnetic field involving synthetic dimensions associated with the atomic internal degrees of freedom [6]. [1] M. Lewenstein, A. Sanpera, V.
