Talk Title: Novel types of van der Waals interactions between ultracold molecules

Abstract:
In this talk I will discuss novel type of van der Waals (vdW) interactions; rotational vdW [1], hyperfine vdW [2], and ro-vibrational vdW [3]. For typical ultracold molecules these can dominate over the "usual" vdW interaction (or electronic vdW). I will discuss various applications including evaporation, quantum simulation, impurity physics, and deterministic loading of molecules into tweezer arrays [4,5].
