Hydrodynamics in lattice models with continuous non-Abelian symmetries
Paolo Glorioso, Luca V. Delacrétaz, Xiao Chen +2
We develop a systematic effective field theory of hydrodynamics for many-body systems on the lattice with global continuous non-Abelian symmetries. Models with continuous non-Abeli…
Superfluids as Higher-form Anomalies
Luca V. Delacrétaz, Diego M. Hofman, Grégoire Mathys
We recast superfluid hydrodynamics as the hydrodynamic theory of a system with an emergent anomalous higher-form symmetry. The higher-form charge counts the winding planes of the s…
Theory of the collective magnetophonon resonance and melting of the field-induced Wigner solid
Luca V. Delacrétaz, Blaise Goutéraux, Sean A. Hartnoll +1
Electron solid phases of matter are revealed by characteristic vibrational resonances. Sufficiently large magnetic fields can overcome the effects of disorder, leading to a weakly…
Theory of the supercyclotron resonance and Hall response in anomalous 2d metals
Luca V. Delacrétaz, Sean A. Hartnoll
Weakly disordered superconducting films can be driven into an anomalous low temperature resistive state upon applying a magnetic field. Recent experiments on weakly disordered amor…
