Generating Steady Topologically Non-Trivial Artificial Spin Texture with Cold Atoms

Abstract

In this article we proposed a scheme to generating steady topologically non-trivial artificial spin texture in cold atom systems. An example of generating a texture of charge one skyrmion with Laguerre-Gaussian beam was given. It provides a scheme for studying skyrmion excitations of quantum Hall ferromagnetism in cold atom systems.
