Correlation functions and transport coefficients in generalised hydrodynamics

J De Nardis, B Doyon, M Medenjak… - Journal of Statistical …, 2022 - iopscience.iop.org
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 Drude …

Emergence of hydrodynamic spatial long-range correlations in nonequilibrium many-body systems

B Doyon, G Perfetto, T Sasamoto, T Yoshimura - Physical Review Letters, 2023 - APS
At large scales of space and time, the nonequilibrium dynamics of local observables in
extensive many-body systems is well described by hydrodynamics. At the Euler scale, one …

Exact entanglement growth of a one-dimensional hard-core quantum gas during a free expansion

S Scopa, A Krajenbrink, P Calabrese… - Journal of Physics A …, 2021 - iopscience.iop.org
We consider the non-equilibrium dynamics of the entanglement entropy of a one-
dimensional quantum gas of hard-core particles, initially confined in a box potential at zero …

On Landauer–Büttiker formalism from a quantum quench

O Gamayun, Y Zhuravlev, N Iorgov - Journal of Physics A …, 2023 - iopscience.iop.org
We study transport in the free fermionic one-dimensional systems subjected to arbitrary local
potentials. The bias needed for the transport is modeled by the initial highly non-equilibrium …

Entanglement Rényi entropies from ballistic fluctuation theory: The free fermionic case

G Del Vecchio Del Vecchio, B Doyon… - SciPost Physics Core, 2024 - scipost.org
The large-scale behaviour of entanglement entropy in finite-density states, in and out of
equilibrium, can be understood using the physical picture of particle pairs. However, the full …

Wigner dynamics for quantum gases under inhomogeneous gain and loss processes with dephasing

M Coppola, GT Landi, D Karevski - Physical Review A, 2023 - APS
We present a Wigner function-based approach for the particle density evolution in fermionic
and bosonic open quantum many-body systems, including the effects of dephasing. In …

Quench dynamics of noninteracting fermions with a delta impurity

G Gouraud, P Le Doussal… - Journal of Physics A …, 2022 - iopscience.iop.org
We study the out-of-equilibrium dynamics of noninteracting fermions in one dimension and
in continuum space, in the presence of a delta impurity potential at the origin whose strength …

Random Matrix Statistics in Propagating Correlation Fronts of Fermions

K Fujimoto, T Sasamoto - Physical Review Letters, 2024 - APS
We theoretically study propagating correlation fronts in noninteracting fermions on a one-
dimensional lattice starting from an alternating state, where the fermions occupy every other …

Conditional no-jump dynamics of noninteracting quantum chains

M Coppola, D Karevski, GT Landi - Physical Review B, 2024 - APS
Lindbladian dissipative processes can be determined by stochastic samplings of individual
trajectories, whose non-Hermitian evolution is perturbed by quantum jumps. The conditional …

Transport phenomena and correlation dynamics of a one-dimensional effective Hamiltonian equivalent to the hexagonal Harper model

S Dhara, D Sahu, M Singh, S Gangadharaiah - Physical Review B, 2024 - APS
The phase diagram of the one-dimensional hexagonal Harper (HH) model reveals the
presence of two metallic phases and one insulating phase, separated by critical lines and a …
