Relaxation dynamics in a long-range system with mixed Hamiltonian and non-Hamiltonian interactions
Alessandro Campa, Shamik Gupta
Sometimes the dynamics of a physical system is described by non-Hamiltonian equations of motion, and additionally, the system is characterized by long-range interactions. A concret…

The study of the dynamics of the order parameter of coupled oscillators in the Ott-Antonsen scheme for generic frequency distributions
Alessandro Campa
The Ott-Antonsen ansatz shows that, for certain classes of distribution of the natural frequencies in systems of globally coupled Kuramoto oscillators, the dynamics of the orde…

Modified Thirring model beyond the excluded-volume approximation
Alessandro Campa, Lapo Casetti, Pierfrancesco Di Cintio +3
Long-range interacting systems may exhibit ensemble inequivalence and can possibly attain equilibrium states under completely open conditions, for which energy, volume and number o…
