Entanglement propagation and dynamics in non-additive quantum systems
Guido Giachetti, Nicolo Defenu
The prominent collective character of long-range interacting quantum systems makes them promising candidates for quantum technological applications. Yet, lack of additivity overthr…
Symplectic coarse graining approach to the dynamics of spherical self-gravitating systems
Luca Barbieri, Pierfrancesco Di Cintio, Guido Giachetti +2
We investigate the evolution of the phase-space distribution function around slightly perturbed stationary states and the process of violent relaxation in the context of the dissip…
Violent relaxation in the Hamiltonian mean field model: II. Non-equilibrium phase diagrams
Alessandro Santini, Guido Giachetti, Lapo Casetti
A classical long-range-interacting -particle system relaxes to thermal equilibrium on time scales growing with ; in the limit such a relaxation time diverges. H…
Berezinskii-Kosterlitz-Thouless phase transitions with long-range couplings
Guido Giachetti, Nicolo Defenu, Stefano Ruffo +1
The Berezinskii-Kostelitz-Thouless (BKT) transition is the paradigmatic example of a topological phase transition without symmetry-breaking, where a quasi-ordered phase, characteri…
