Title: Rotated Superfluids EFT
Abstract:
I will discuss effective field theory of a vortex lattice in a two-dimensional rotating superfluid, and its description in terms of a compact Lifshitz theory augmented with a Berry phase term, encoding the vortex dynamics in the presence of a superflow. I will then describe its formulations in terms of a traceless symmetric scalar-charge theory dual, and discuss its multipole one-form symmetries. Examining its topological crystalline defects with restricted mobility, I will describe descendant phases, which includes a novel "vortex supersolid" and develop the dual gauge theory for the quantum melting transition from a vortex crystal to a vortex supersolid.
