Classical Goldstone modes in Long-Range Interacting Systems
Tarcisio M Rocha Filho, Bruno Marcos
For a classical system with long-range interactions, a soft mode exists whenever a stationary state spontaneously breaks a continuous symmetry of the Hamiltonian. Besides that, if…
Formation and relaxation of quasi-stationary states in particle systems with power law interactions
Bruno Marcos, Andrea Gabrielli, Michael Joyce
We explore the formation and relaxation of so-called quasi-stationary states (QSS) for particle distributions in three dimensions interacting via an attractive radial pair potentia…
Cold uniform spherical collapse revisited
M. Joyce, B. Marcos, F. Sylos Labini
We report results of a study of the Newtonian dynamics of N self-gravitating particles which start in a quasi-uniform spherical configuration, without initial velocities. These ini…
Quasi-stationary states and the range of pair interactions
Andrea Gabrielli, Michael Joyce, Bruno Marcos
"Quasi-stationary" states are approximately time-independent out of equilibrium states which have been observed in a variety of systems of particles interacting by long-range inter…
A dynamical classification of the range of pair interactions
Andrea Gabrielli, Michael Joyce, Bruno Marcos +1
We formalize a classification of pair interactions based on the convergence properties of the {\it forces} acting on particles as a function of system size. We do so by considering…
Causality constraints on fluctuations in cosmology: a study with exactly solvable one dimensional models
A. Gabrielli, M. Joyce, B. Marcos +1
A well known argument in cosmology gives that the power spectrum (or structure function) of mass density fluctuations produced from a uniform initial state by physics which…
