Spontaneous symmetry breaking at any temperature in a local one-dimensional model
Andrew Lucas
We present a one-dimensional classical statistical physics model on an infinite lattice with nearest-neighbor interactions and local state space , with a ``helical" s…
Interaction corrections to topological density three-point functions in two-dimensional Fermi liquids: a coadjoint orbit perspective
Akshay Pal, Andrew Lucas, Umang Mehta
Density three-point correlations are known to probe the topology of the Fermi sea in two-dimensional noninteracting systems. Here, we study how these correlations are modified by i…
Non-perturbative saturation of Krylov complexity, and its implications in quantum gravity
Andrew Lucas, Amit Vikram
We study the dynamics of Krylov state complexity in finite-dimensional quantum systems. Orthogonal polynomials built on a discrete energy spectrum crowd away from regions where the…
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…
On the reconstruction map in JT gravity
Chris Akers, Andrew Lucas, Amit Vikram
An open question in AdS/CFT is how to reconstruct semiclassical bulk operators precisely enough that non-perturbative quantum effects can be computed. We propose a set of physicall…
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…
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…
