Simulating generalised fluids via interacting wave packets evolution
Andrew Urilyon, Leonardo Biagetti, Jitendra Kethepalli +1
One-dimensional integrable and quasi-integrable systems display, on macroscopic scales, a universal form of transport known as Generalized Hydrodynamics (GHD). In its standard Eule…
Diffusive hydrodynamics of hard rods from microscopics
Friedrich Hübner, Leonardo Biagetti, Jacopo De Nardis +1
We derive exact equations governing the large-scale dynamics of hard rods, including diffusive effects that go beyond ballistic transport. Diffusive corrections are the first-order…
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…
Bound-state confinement after trap-expansion dynamics in integrable systems
Leonardo Biagetti, Vincenzo Alba
Integrable systems possess stable families of quasiparticles, which are composite objects (bound states) of elementary excitations. Motivated by recent quantum computer experiments…
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…
