Minimal Models of Entropic Order
Xiaoyang Huang, Zohar Komargodski, Andrew Lucas +2
Due to entropic effects, it is possible that generic high-energy states of a quantum or classical system are ordered. This leads to spontaneous symmetry breaking at arbitrarily hig…
Quantum geometry from the Moyal product: quantum kinetic equation and non-linear response
Takamori Park, Xiaoyang Huang, Lucile Savary +1
We systematically derive the dissipationless quantum kinetic equation for a multi-band free fermionic system with U(1) symmetry. Using the Moyal product formalism, we fully band-di…
Entropic Order
Yiqiu Han, Xiaoyang Huang, Zohar Komargodski +2
Ordered phases of matter, such as solids, ferromagnets, superfluids, or quantum topological order, typically only exist at low temperatures. Despite this conventional wisdom, we pr…
Breakdown of hydrodynamics in a Galilean quantum Hall crystal
Xiaoyang Huang, Andrew Lucas
We construct a nonlinear fluctuating hydrodynamic effective field theory for Galilean-invariant quantum Hall systems with spontaneously broken translational symmetry. Neglecting th…
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…
Effective field theory of Berry Fermi liquid from the coadjoint orbit method
Xiaoyang Huang
We construct an effective field theory for an interacting Fermi liquid with nonzero Berry curvature at zero temperature, called the Berry Fermi liquid. We start with the extended p…
Generalized time-reversal symmetry and effective theories for nonequilibrium matter
Xiaoyang Huang, Jack H. Farrell, Aaron J. Friedman +3
The past decade has witnessed the development of systematic effective theories for dissipative thermal systems. Here, we describe an analogous effective theory framework that appli…
Disordered quantum critical fixed points from holography
Xiaoyang Huang, Subir Sachdev, Andrew Lucas
Using holographic duality, we present an analytically controlled theory of quantum critical points without quasiparticles, at finite disorder and finite charge density. These fixed…
Goldstone bosons and fluctuating hydrodynamics with dipole and momentum conservation
Paolo Glorioso, Xiaoyang Huang, Jinkang Guo +2
We develop a Schwinger-Keldysh effective field theory describing the hydrodynamics of a fluid with conserved charge and dipole moments, together with conserved momentum. The result…
Hydrodynamic effective field theories with discrete rotational symmetry
Xiaoyang Huang, Andrew Lucas
We develop a hydrodynamic effective field theory on the Schwinger-Keldysh contour for fluids with charge, energy, and momentum conservation, but only discrete rotational symmetry.…
Fingerprints of quantum criticality in locally resolved transport
Xiaoyang Huang, Andrew Lucas
Understanding electrical transport in strange metals, including the seeming universality of Planckian -linear resistivity, remains a longstanding challenge in condensed matter p…
Electron-phonon hydrodynamics
Xiaoyang Huang, Andrew Lucas
We develop the theory of hydrodynamics of an isotropic Fermi liquid of electrons coupled to isotropic acoustic phonons, assuming that umklapp processes may be neglected. At low tem…
