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].
