Diffusion cascade in a model of interacting random walkers
Abhishek Raj, Paolo Glorioso, Sarang Gopalakrishnan +1
We consider the relaxation of finite-wavevector density waves in a facilitated classical lattice gas. Linear hydrodynamics predicts that such perturbations should relax exponential…
The Unreasonable Ineffectiveness of the Deeper Layers
Andrey Gromov, Kushal Tirumala, Hassan Shapourian +2
How is knowledge stored in an LLM's weights? We study this via layer pruning: if removing a certain layer does not affect model performance in common question-answering benchmarks,…
Space-time generalization of mutual information
Paolo Glorioso, Xiao-Liang Qi, Zhenbin Yang
The mutual information characterizes correlations between spatially separated regions of a system. Yet, in experiments we often measure dynamical correlations, which involve probin…
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…
Kardar-Parisi-Zhang Universality at the Edge of Laughlin States
Gustavo M. Monteiro, Dylan Reynolds, Paolo Glorioso +1
In this letter, we investigate the dissipative dynamics at the edge of Laughlin fractional quantum Hall (FQH) states starting from the hydrodynamic framework of the composite Boson…
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…
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…
Far-from-equilibrium universality in two-dimensional Heisenberg antiferromagnets
Zhaoyi Li, Paolo Glorioso, Joaquin F. Rodriguez-Nieva
We study the far-from-equilibrium dynamics of isolated two-dimensional Heisenberg antiferromagnets. We consider spin spiral initial conditions which imprint a position-dependent st…
Flatter, faster: scaling momentum for optimal speedup of SGD
Aditya Cowsik, Tankut Can, Paolo Glorioso
Commonly used optimization algorithms often show a trade-off between good generalization and fast training times. For instance, stochastic gradient descent (SGD) tends to have good…
Cross Entropy Benchmark for Measurement-Induced Phase Transitions
Yaodong Li, Yijian Zou, Paolo Glorioso +2
We investigate the prospects of employing the linear cross-entropy to experimentally access measurement-induced phase transitions (MIPT) without requiring any postselection of quan…
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…
Joule heating in bad and slow metals
Paolo Glorioso, Sean A. Hartnoll
Heat supplied to a metal is absorbed by the electrons and then transferred to the lattice. In conventional metals energy is released to the lattice by phonons emitted from the Lind…
Breakdown of hydrodynamics below four dimensions in a fracton fluid
Paolo Glorioso, Jinkang Guo, Joaquin F. Rodriguez-Nieva +1
We present the nonlinear fluctuating hydrodynamics which governs the late time dynamics of a chaotic many-body system with simultaneous charge/mass, dipole/center of mass, and mome…
Gauging anomalous unitary operators
Yuhan Liu, Hassan Shapourian, Paolo Glorioso +1
Boundary theories of static bulk topological phases of matter are obstructed in the sense that they cannot be realized on their own as isolated systems. The obstruction can be quan…
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…
Breakdown of Diffusion on the Edge
Luca V. Delacretaz, Paolo Glorioso
We show that dirty Quantum Hall systems exhibit large hydrodynamic fluctuations at their edge that lead to anomalously damped charge excitations in the Kardar-Parisi-Zhang universa…
Effective response theory for Floquet topological systems
Paolo Glorioso, Andrey Gromov, Shinsei Ryu
We present an effective field theory approach to the topological response of Floquet systems with symmetry group . This is achieved by introducing a background gauge field i…
A prescription for holographic Schwinger-Keldysh contour in non-equilibrium systems
Paolo Glorioso, Michael Crossley, Hong Liu
We develop a prescription for computing real-time correlation functions defined on a Schwinger-Keldysh contour for non-equilibrium systems using gravity. The prescription involves…
Effective field theory of magnetohydrodynamics from generalized global symmetries
Paolo Glorioso, Dam Thanh Son
We introduce an effective action for non-dissipative magnetohydrodynamics. A crucial guiding principle is the generalized global symmetry of electrodynamics, which naturally leads…
Lectures on non-equilibrium effective field theories and fluctuating hydrodynamics
Paolo Glorioso, Hong Liu
We review recent progress in developing effective field theories (EFTs) for non-equilibrium processes at finite temperature, including a new formulation of fluctuating hydrodynamic…
Ghostbusters: Unitarity and Causality of Non-equilibrium Effective Field Theories
Ping Gao, Paolo Glorioso, Hong Liu
For a non-equilibrium physical system defined along a closed time path (CTP), a key constraint is the so-called largest time equation, which is a consequence of unitarity and impli…

Paolo Glorioso, Hong Liu, Srivatsan Rajagopal
We derive effective actions for parity-violating fluids in both and dimensions, including those with anomalies. As a corollary we confirm the most general constitut…
Effective field theory for dissipative fluids (II): classical limit, dynamical KMS symmetry and entropy current
Paolo Glorioso, Michael Crossley, Hong Liu
In this paper we further develop the fluctuating hydrodynamics proposed in arXiv:1511.03646 in a number of ways. We first work out in detail the classical limit of the hydrodynamic…
The second law of thermodynamics from symmetry and unitarity
Paolo Glorioso, Hong Liu
The second law of thermodynamics states that for a thermally isolated system entropy never decreases. Most physical processes we observe in nature involve variations of macroscopic…
