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…

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…
