Heisenberg-limited metrology with perturbing interactions
Chao Yin, Andrew Lucas
We show that it is possible to perform Heisenberg-limited metrology on GHZ-like states, in the presence of generic spatially local, possibly strong interactions during the measurem…
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…
Polynomial-time classical sampling of high-temperature quantum Gibbs states
Chao Yin, Andrew Lucas
The computational complexity of simulating quantum many-body systems generally scales exponentially with the number of particles. This enormous computational cost prohibits first p…
Symplectic geometry and circuit quantization
Andrew Osborne, Trevyn Larson, Sarah Jones +3
Circuit quantization is an extraordinarily successful theory that describes the behavior of quantum circuits with high precision. The most widely used approach of circuit quantizat…
Fracton superfluid hydrodynamics
Charles Stahl, Marvin Qi, Paolo Glorioso +2
We examine the hydrodynamics of systems with spontaneously broken multipolar symmetries using a systematic effective field theory. We focus on the simplest non-trivial setting: a s…
Speed limits and locality in many-body quantum dynamics
Chi-Fang Chen, Andrew Lucas, Chao Yin
We review the mathematical speed limits on quantum information processing in many-body systems. After the proof of the Lieb-Robinson Theorem in 1972, the past two decades have seen…
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…
Anomalous hydrodynamics with triangular point group in 2 + 1 dimensions
Marvin Qi, Jinkang Guo, Andrew Lucas
We present a theory of hydrodynamics for a vector U(1) charge in 2+1 dimensions, whose rotational symmetry is broken to the point group of an equilateral triangle. We show that it…
Prethermalization and the local robustness of gapped systems
Chao Yin, Andrew Lucas
We prove that prethermalization is a generic property of gapped local many-body quantum systems, subjected to small perturbations, in any spatial dimension. More precisely, let $H_…
Hydrodynamics with helical symmetry
Jack H. Farrell, Xiaoyang Huang, Andrew Lucas
We present the hydrodynamics of fluids in three spatial dimensions with helical symmetry, wherein only a linear combination of a rotation and translation is conserved in one of the…
Locality and error correction in quantum dynamics with measurement
Aaron J. Friedman, Chao Yin, Yifan Hong +1
The speed of light sets a strict upper bound on the speed of information transfer in both classical and quantum systems. In nonrelativistic quantum systems, the Lieb-Robinson T…
Quantum error correction in a time-dependent transverse field Ising model
Yifan Hong, Jeremy T. Young, Adam M. Kaufman +1
We describe a simple quantum error correcting code built out of a time-dependent transverse field Ising model. The code is similar to a repetition code, but has two advantages: an…
Fracton magnetohydrodynamics
Marvin Qi, Oliver Hart, Aaron J. Friedman +2
We extend recent work on hydrodynamics with global multipolar symmetries -- known as "fracton hydrodynamics" -- to systems in which the multipolar symmetries are gauged. We refer t…
Fracton hydrodynamics without time-reversal symmetry
Jinkang Guo, Paolo Glorioso, Andrew Lucas
We present an effective field theory for the nonlinear fluctuating hydrodynamics of a single conserved charge with or without time-reversal symmetry, based on the Martin-Siggia-Ros…
Analogue viscous current flow near the onset of superconductivity
Koushik Ganesan, Andrew Lucas
Spatially resolved transport in two-dimensional quantum materials can reveal dynamics which is invisible in conventional bulk transport measurements. We predict striking patterns i…
Non-equilibrium phase transitions in competitive markets caused by network effects
Andrew Lucas
Network effects are the added value derived solely from the popularity of a product in an economic market. Using agent-based models inspired by statistical physics, we propose a mi…
Snowmass White Paper: New ideas for many-body quantum systems from string theory and black holes
Mike Blake, Yingfei Gu, Sean A. Hartnoll +5
During the last two decades many new insights into the dynamics of strongly coupled quantum many-body systems have been obtained using gauge/gravity duality, with black holes often…
Hydrodynamics with triangular point group
Aaron J. Friedman, Caleb Q. Cook, Andrew Lucas
When continuous rotational invariance of a two-dimensional fluid is broken to the discrete, dihedral subgroup - the point group of an equilateral triangle - the resulting ani…
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.…
Infinite families of fracton fluids with momentum conservation
Andrew Osborne, Andrew Lucas
We construct infinite families of new universality classes of fracton hydrodynamics with momentum conservation, both with multipole conservation laws and/or subsystem symmetry. We…
Renormalization group in quantum critical theories with Harris-marginal disorder
Koushik Ganesan, Andrew Lucas, Leo Radzihovsky
We develop a renormalization group for weak Harris-marginal disorder in otherwise strongly interacting quantum critical theories, focusing on systems which have emergent conformal…
Imaging the breakdown of ohmic transport in graphene
A. Jenkins, S. Baumann, H. Zhou +7
Ohm's law describes the proportionality of current density and electric field. In solid-state conductors, Ohm's law emerges due to electron scattering processes that relax the elec…
The NEOWISE-Discovered Comet Population and the CO+CO2 production rates
James M. Bauer, Rachel Stevenson, Emily Kramer +19
The 163 comets observed during the WISE/NEOWISE prime mission represent the largest infrared survey to date of comets, providing constraints on dust, nucleus sizes, and CO+CO2 prod…

James M. Bauer, Tommy Grav, Erin Blauvelt +22
The Wide-field Infrared Survey Explorer (WISE) observed 52 Centaurs and Scattered Disk Objects in the thermal infrared, including the 15 discoveries that were new. We present analy…
