Dynamical Gauge Fields in Ultracold Atomic Mixtures
December 9th, 2019 APOORVA HEGDE Universität Heidelberg

Gauge theories form the fundamental building block of High Energy Physics. They are essential for the describing the interaction of elementary particles through gauge fields. We use a mixture of ultracold sodium and lithium atoms to engineer a building block for the quantum simulation of such dynamical gauge fields. We associate the matter field with lithium atoms and the gauge field with sodium atoms. Local gauge invariance, which is of central importance when describing gauge theories is achieved in this experiment by interspecies spin changing collisions, which locally conserves angular momentum. The building block thus realized can be further extended a 1D system.
