Generalized Hydrodynamics of Bloch Oscillations in the Absence of a Lattice
Stefano Scopa, Philip Zechmann, Michael Knap +2
Objects subjected to a constant force generally increase their velocity over time. This expectation fails whenever their energy is a smooth and periodic function of momentum, resul…
Squeezed ensembles and anomalous dynamic roughening in interacting integrable chains
Guillaume Cecile, Jacopo De Nardis, Enej Ilievski
It is widely accepted that local subsystems in isolated integrable quantum systems equilibrate to generalized Gibbs ensembles. Here, we demonstrate the failure of canonical general…
Non-linear fluctuating hydrodynamics for KPZ scaling in isotropic spin chains
Jacopo De Nardis, Sarang Gopalakrishnan, Romain Vasseur
Finite temperature spin transport in integrable isotropic spin chains is known to be superdiffusive, with dynamical spin correlations that are conjectured to fall into the Kardar-P…
Hydrodynamic relaxation of spin helices
Guillaume Cecile, Sarang Gopalakrishnan, Romain Vasseur +1
Motivated by recent cold atom experiments, we study the relaxation of spin helices in quantum XXZ spin chains. The experimentally observed relaxation of spin helices follows scalin…
A dynamical theory for one-dimensional fermions with strong two-body losses: universal non-Hermitian Zeno physics and spin-charge separation
Lorenzo Rosso, Alberto Biella, Jacopo De Nardis +1
We study an interacting one-dimensional gas of spin-1/2 fermions with two-body losses. The dynamical phase diagram that characterises the approach to the stationary state displays…
Thermalisation of a trapped one-dimensional Bose gas via diffusion
Alvise Bastianello, Andrea De Luca, Benjamin Doyon +1
For a decade the fate of a one-dimensional gas of interacting bosons in an external trapping potential remained mysterious. We here show that whenever the underlying integrability…
Edge singularities and quasi-long-range order in non-equilibrium steady states
Jacopo De Nardis, Miłosz Panfil
The singularities of the dynamical response function are one of the most remarkable effects in many-body interacting systems. However in one dimension these divergences only exist…
Particle-hole pairs and density-density correlations in the Lieb-Liniger model
Jacopo De Nardis, Miłosz Panfil
We review the recently introduced thermodynamic form factors for pairs of particle-hole excitations on finite-entropy states in the Lieb-Liniger model. We focus on the density oper…
Probing non-thermal density fluctuations in the one-dimensional Bose gas
Jacopo De Nardis, Miłosz Panfil, Andrea Gambassi +3
Quantum integrable models display a rich variety of non-thermal excited states with unusual properties. The most common way to probe them is by performing a quantum quench, i.e., b…
Exact correlations in the Lieb-Liniger model and detailed balance out-of-equilibrium
Jacopo De Nardis, Miłosz Panfil
We study the density-density correlation function of the 1D Lieb-Liniger model and obtain an exact expression for the small momentum limit of the static correlator in the thermodyn…
Separation of Timescales in a Quantum Newton's Cradle
R. van den Berg, B. Wouters, S. Eliëns +3
For strongly repulsive bosons in one dimension, we provide detailed modeling of the Bragg pulse used in quantum Newton's cradle-like settings or in Bragg spectroscopy experiments.…
Relaxation dynamics of local observables in integrable systems
Jacopo De Nardis, Lorenzo Piroli, Jean-Sébastien Caux
We show, using the quench action approach [Caux&Essler Phys. Rev. Lett. 110 (2013)], that the whole post-quench time evolution of an integrable system in the thermodynamic limit ca…
Density form factors of the 1D Bose gas for finite entropy states
Jacopo De Nardis, Miłosz Panfil
We consider the Lieb-Liniger model for a gas of bosonic interacting particles. Using Algebraic Bethe Ansatz results we compute the thermodynamic limit of the form factors of th…
Analytical expression for a post-quench time evolution of the one-body density matrix of one-dimensional hard-core bosons
Jacopo De Nardis, Jean-Sébastien Caux
We apply the logic of the quench action to give an exact analytical expression for the time evolution of the one-body density matrix after an interaction quench in the Lieb-Liniger…
Metastable criticality and the super Tonks-Girardeau gas
Miłosz Panfil, Jacopo De Nardis, Jean-Sébastien Caux
We consider a 1D Bose gas with attractive interactions in an out-of-equilibrium highly excited state containing no bound states. We show that relaxation processes in the gas are su…
