Towards an ab initio derivation of generalised hydrodynamics from a gas of interacting wave packets
Benjamin Doyon, Friedrich Hübner
We present steps towards an ab initio derivation of generalised hydrodynamics in quantum integrable models, starting from the Bethe wave functions, and explained on the example of…
Exact large-scale fluctuations of the phase field in the sine-Gordon model
Giuseppe Del Vecchio Del Vecchio, Márton Kormos, Benjamin Doyon +1
We present the first exact theory and analytical formulas for the large-scale phase fluctuations in the sine-Gordon model, valid in all regimes of the field theory, for arbitrary t…
Soliton Gas: Theory, Numerics and Experiments
Pierre Suret, Stephane Randoux, Andrey Gelash +3
The concept of soliton gas was introduced in 1971 by V. Zakharov as an infinite collection of weakly interacting solitons in the framework of Korteweg-de Vries (KdV) equation. In t…
Entanglement Rényi Entropies from Ballistic Fluctuation Theory: the free fermionic case
Giuseppe Del Vecchio Del Vecchio, Benjamin Doyon, Paola Ruggiero
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…
Hydrodynamic gauge fixing and higher order hydrodynamic expansion
Jacopo De Nardis, Benjamin Doyon
Hydrodynamics is a powerful emergent theory for the large-scale behaviours in many-body systems, quantum or classical. It is a gradient series expansion, where different orders of…
Emergence of hydrodynamic spatial long-range correlations in nonequilibrium many-body systems
Benjamin Doyon, Gabriele Perfetto, Tomohiro Sasamoto +1
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 assum…
