Ultracold Dipolar Molecules: Control with Fields and Applications

Abstract

Ultracold dipolar molecules are excellent candidates for engineering quantum applications and controlled chemistry [1]. Therefore a lot of effort is devoted nowadays to produce ground state ultracold molecules in high densities as well as to understand their properties and ways of control [2]. The tools of control available in experiments are for example electric, magnetic and electromagnetic fields. In this talk, I will present recent theoretical and experimental results using these tools of control for different applications such as the formation of long-lived dipolar gases [3], ultracold chemistry [4] and prospects for new states of matter [5]. I will especially focus on the electric field shielding of molecules against destructive collisions [3].
