Hydrodynamics as the effective field theory of strong-to-weak spontaneous symmetry breaking
Xiaoyang Huang, Marvin Qi, Jian-Hao Zhang +1
Inspired by the hunt for new phases of matter in quantum mixed states, it has recently been proposed that the equivalence of microcanonical and canonical ensembles in statistical m…

Effective field theory for ersatz Fermi liquids
Xiaoyang Huang, Andrew Lucas, Umang Mehta +1
We apply "hydrodynamic" effective field theory techniques to an ersatz Fermi liquid. Our effective theory, which captures the correlation functions of density operators at each ang…

Kinematically constrained vortex dynamics in charge density waves
Marvin Qi, Andrew Lucas
We build a minimal model of dissipative vortex dynamics in two spatial dimensions, subject to a kinematic constraint: dipole conservation. The additional conservation law implies a…
