Dipolar interactions of lattice-confined polar molecules

COFFEE_KLATCH · Invited

Abstract

Long-range dipolar interactions can be used to realize lattice spin models for exploring quantum magnetism. I will discuss experiments where we observe dipolar spin-exchange interactions for ultracold KRb molecules confined in a deep three-dimensional optical lattice. The long-range dipolar interactions exist even in the absence of tunneling and extend beyond nearest neighbors. This enables coherent spin dynamics even for gases with relatively low lattice filling.
