Euler-scale dynamical fluctuations in non-equilibrium interacting integrable systems
Gabriele Perfetto, Benjamin Doyon
We derive an exact formula for the scaled cumulant generating function of the time-integrated current associated to an arbitrary ballistically transported conserved charge. Our res…
Dynamics of large deviations in the hydrodynamic limit: Non-interacting systems
Gabriele Perfetto, Andrea Gambassi
We study the dynamics of the statistics of the energy transferred across a point along a quantum chain which is prepared in the inhomogeneous initial state obtained by joining two…
Euler-scale dynamical correlations in integrable systems with fluid motion
Frederik S. Møller, Gabriele Perfetto, Benjamin Doyon +1
We devise an iterative scheme for numerically calculating dynamical two-point correlation functions in integrable many-body systems, in the Eulerian scaling limit. Expressions for…
Quasilocalized dynamics from confinement of quantum excitations
Alessio Lerose, Federica Maria Surace, Paolo Pietro Mazza +3
Confinement of excitations induces quasilocalized dynamics in disorder-free isolated quantum many-body systems in one spatial dimension. This occurrence is signalled by severe supp…
Quench action and large deviations: work statistics in the one-dimensional Bose gas
Gabriele Perfetto, Lorenzo Piroli, Andrea Gambassi
We study the statistics of large deviations of the intensive work done in an interaction quench of a one-dimensional Bose gas with a large number N of particles, system size L and…
Suppression of transport in non-disordered quantum spin chains due to confined excitations
Paolo Pietro Mazza, Gabriele Perfetto, Alessio Lerose +2
The laws of thermodynamics require any initial macroscopic inhomogeneity in extended many-body systems to be smoothed out by the time evolution through the activation of transport…
