Damping of Pseudo-Goldstone Fields
Luca V. Delacrétaz, Blaise Goutéraux, Vaios Ziogas
Approximate symmetries abound in Nature. If these symmetries are also spontaneously broken, the would-be Goldstone modes acquire a small mass, or inverse correlation length, and ar…
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…
Theory of hydrodynamic transport in fluctuating electronic charge density wave states
Luca V. Delacrétaz, Blaise Goutéraux, Sean A. Hartnoll +1
We describe the collective hydrodynamic motion of an incommensurate charge density wave state in a clean electronic system. Our description simultaneously incorporates the effects…
Bad Metals from Fluctuating Density Waves
Luca V. Delacrétaz, Blaise Goutéraux, Sean A. Hartnoll +1
Bad metals have a large resistivity without being strongly disordered. In many bad metals the Drude peak moves away from zero frequency as the resistivity becomes large at increasi…
Hydrodynamic theory of quantum fluctuating superconductivity
Richard A. Davison, Luca V. Delacrétaz, Blaise Goutéraux +1
A hydrodynamic theory of transport in quantum mechanically phase-disordered superconductors is possible when supercurrent relaxation can be treated as a slow process. We obtain gen…
