Nonlinear Fluctuating Hydrodynamics from Interacting Noisy Quantum Matter
Alexios Christopoulos, João Costa, Stefano Scopa +4
A universal characterization of non-equilibrium steady states in interacting quantum many-body systems remains one of the central challenges of statistical physics. Here, we addres…
An exactly solvable macroscopic fluctuation theory of single-file diffusion
Sandeep Jangid, Soumyabrata Saha, Kapil Sharma +4
Single-file diffusion is a ubiquitous phenomenon in low-dimensional systems, arising in transport inside narrow channels. Its natural continuum model is a one-dimensional gas of ex…
Enhanced correlations due to ballistic transport
Damiano De Angelis, Jacopo De Nardis, Stefano Scopa
We investigate the nature of density-density correlations in a 1D gas of hard-core particles initially prepared at equilibrium (either at zero or finite temperature) on a semi-infi…
Diffusive hydrodynamics from long-range correlations
Friedrich Hübner, Leonardo Biagetti, Jacopo De Nardis +1
In the hydrodynamic theory, the non-equilibrium dynamics of a many-body system is approximated, at large scales of space and time, by irreversible relaxation to local entropy maxim…
Generalised BBGKY hierarchy for near-integrable dynamics
Leonardo Biagetti, Maciej Lebek, Milosz Panfil +1
We study quantum and classical many-body Hamiltonian systems that combine integrable contact interactions with generic long-range two-body potentials. Starting from an ansatz for t…
Partial yet definite emergence of the Kardar-Parisi-Zhang class in isotropic spin chains
Kazumasa A. Takeuchi, Kazuaki Takasan, Ofer Busani +3
Integrable spin chains with a continuous non-Abelian symmetry, such as the one-dimensional isotropic Heisenberg model, show superdiffusive transport with little theoretical underst…
Quantum fluctuating theory for one-dimensional shock waves
Andrew Urilyon, Stefano Scopa, Giuseppe Del Vecchio Del Vecchio +1
We study the formation and the subsequent dynamics of shock waves in repulsive one-dimensional Bose gases during the free expansion of a density hump. By building coherent Fermi st…
Measurement-induced phase transitions by matrix product states scaling
Guillaume Cecile, Hugo Lóio, Jacopo De Nardis
We study the time evolution of long quantum spin chains subjected to continuous monitoring via matrix product states (MPS) at fixed bond dimension, with the Time-Dependent Variatio…
Three-stage thermalisation of a quasi-integrable system
Leonardo Biagetti, Guillaume Cecile, Jacopo De Nardis
We consider a system of classical hard rods or billiard balls in one dimension, initially prepared in a Bragg-pulse state at a given temperature and subjected to external periodic…
Purification Timescales in Monitored Fermions
Hugo Lóio, Andrea De Luca, Jacopo De Nardis +1
We investigate the crucial role played by a global symmetry in the purification timescales and the phase transitions of monitored free fermionic systems separating a mixed and a pu…
Hydrodynamic gauge fixing and higher order hydrodynamic expansion
Jacopo De Nardis, Benjamin Doyon
Hydrodynamics is a powerful emergent theory for the large-scale behaviours in many-body systems, quantum or classical. It is a gradient series expansion, where different orders of…
Subdiffusive hydrodynamics of nearly-integrable anisotropic spin chains
Jacopo De Nardis, Sarang Gopalakrishnan, Romain Vasseur +1
We address spin transport in the easy-axis Heisenberg spin chain subject to integrability-breaking perturbations. We find that spin transport is subdiffusive with dynamical exponen…

Joseph Durnin, Andrea De Luca, Jacopo De Nardis +1
We derive a large-scale hydrodynamic equation, including diffusive and dissipative effects, for systems with generic static position-dependent driving forces coupling to local cons…
Correlation functions and transport coefficients in generalised hydrodynamics
Jacopo De Nardis, Benjamin Doyon, Marko Medenjak +1
We review the recent advances on exact results for dynamical correlation functions at large scales and related transport coefficients in interacting integrable models. We discuss D…
Stability of superdiffusion in nearly integrable spin chains
Jacopo De Nardis, Sarang Gopalakrishnan, Romain Vasseur +1
Superdiffusive finite-temperature transport has been recently observed in a variety of integrable systems with nonabelian global symmetries. Superdiffusion is caused by giant Golds…
Superdiffusion from emergent classical solitons in quantum spin chains
Jacopo De Nardis, Sarang Gopalakrishnan, Enej Ilievski +1
Finite-temperature spin transport in the quantum Heisenberg spin chain is known to be superdiffusive, and has been conjectured to lie in the Kardar-Parisi-Zhang (KPZ) universality…
Universality classes of spin transport in one-dimensional isotropic magnets: the onset of logarithmic anomalies
Jacopo De Nardis, Marko Medenjak, Christoph Karrasch +1
We report a systematic study of finite-temperature spin transport in quantum and classical one-dimensional magnets with isotropic spin interactions, including both integrable and n…
Anomalous spin diffusion in one-dimensional antiferromagnets
Jacopo De Nardis, Marko Medenjak, Christoph Karrasch +1
The problem of characterizing low-temperature spin dynamics in antiferromagnetic spin chains has so far remained elusive. We reinvestigate it by focusing on isotropic antiferromagn…
Hydrodynamic Diffusion in Integrable Systems
Jacopo De Nardis, Denis Bernard, Benjamin Doyon
We show that hydrodynamic diffusion is generically present in many-body interacting integrable models. We extend the recently developed generalised hydrodynamic (GHD) to include te…

We identify a class of one-dimensional spin and fermionic lattice models which display diverging spin and charge diffusion constants, including several paradigmatic models of exact…
Microscopic origin of ideal conductivity in integrable quantum models
