Monte Carlo simulations in the unconstrained ensemble
Ivan Latella, Alessandro Campa, Lapo Casetti +3
The unconstrained ensemble describes completely open systems whose control parameters are chemical potential, pressure, and temperature. For macroscopic systems with short-range in…
Brownian motion of supermassive black holes in galaxy cores
Pierfrancesco Di Cintio, Luca Ciotti, Carlo Nipoti
We investigate the dynamics of supermassive black holes (SMBHs) in galactic cores by means of a semi-analytic model based on the Langevin equation, including dynamical friction and…
-body chaos, phase-space transport and relaxation in numerical simulations
Pierfrancesco Di Cintio, Lapo Casetti
Using direct -body simulations of self-gravitating systems we study the dependence of dynamical chaos on the system size . We find that the -body chaos quantified in terms…
Transport in perturbed classical integrable systems: the pinned Toda chain
Pierfrancesco Di Cintio, Stefano Iubini, Stefano Lepri +1
Nonequilibrium and thermal transport properties of the Toda chain, a prototype of classically integrable system, subject to additional (nonintegrable) terms are considered. In part…
