Crossover from generalized to conventional hydrodynamics in nearly integrable systems under relaxation time approximation
Saikat Santra, Maciej Łebek, Miłosz Panfil
Upon breaking the integrability, the equations of generalized hydrodynamics (GHD) are supplemented by a Boltzmann collision term. Such terms are typically complicated and stem from…
Burgers equation from non-thermal stationary states in nearly-integrable gases
Paweł Lisiak, Maciej Łebek, Miłosz Panfil
When a gas of particles interacts with much a larger reservoir the density dynamics on large scales is typically governed by diffusion. We study this paradigmatic problem for weakl…
Chapman-Enskog theory and crossover between diffusion and superdiffusion for nearly integrable quantum gases
Maciej Łebek, Miłosz Panfil
Integrable systems feature an infinite number of conserved charges and on hydrodynamic scales are described by generalised hydrodynamics (GHD). This description breaks down when th…
Local Properties of the Rapidity Distribution in the Lieb-Liniger Model
Miłosz Panfil, Zoran Ristivojevic
We study the rapidity distribution in the Lieb-Liniger model and derive exact relations for its derivatives at the Fermi level. The latter enables us to treat analytically the free…
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…
Navier-Stokes equations for nearly integrable quantum gases
Maciej Łebek, Miłosz Panfil
The Navier-Stokes equations are paradigmatic equations describing hydrodynamics of an interacting system with microscopic interactions encoded in transport coefficients. In this wo…
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…
The two particle-hole pairs contribution to the dynamic correlation functions of quantum integrable models
Miłosz Panfil
We consider the problem of computing dynamic correlation functions of quantum integrable models employing the thermodynamic form-factor approach. Specifically, we focus on correlat…
Generalized hydrodynamics regime from the thermodynamic bootstrap program
Axel Cortés Cubero, Miłosz Panfil
Within the generalized hydrodynamics (GHD) formalism for quantum integrable models, it is possible to compute simple expressions for a number of correlation functions at the Euleri…
On Truncated Generalized Gibbs Ensembles in the Ising Field Theory
F. H. L. Essler, G. Mussardo, M. Panfil
We discuss the implementation of two different truncated Generalized Gibbs Ensembles (GGE) describing the stationary state after a mass quench process in the Ising Field Theory. On…
Quench Dynamics in Two-Dimensional Integrable SUSY Models
Axel Cortes Cubero, Giuseppe Mussardo, Milosz Panfil
We analyse quench processes in two dimensional quantum field theories with infinite number of conservation laws which also include fermionic charges that close a supersymmetr…
Exact prefactors in static and dynamic correlation functions of 1D quantum integrable models: applications to the Calogero-Sutherland, Lieb-Liniger and XXZ models
Aditya Shashi, Miłosz Panfil, Jean-Sébastien Caux +1
In this article we demonstrate a recently developed technique which addresses the problem of obtaining non-universal prefactors of the correlation functions of 1D systems at zero t…
