Towards quantitative control on discreteness error in the non-linear regime of cosmological N body simulations
Michael Joyce, Bruno Marcos, Thierry Baertschiger
The effects of discreteness arising from the use of the N-body method on the accuracy of simulations of cosmological structure formation are not currently well understood. After a…
Gravitational dynamics of an infinite shuffled lattice: early time evolution and universality of non-linear correlations
Thierry Baertschiger, Michael Joyce, Francesco Sylos Labini +1
In two recent articles a detailed study has been presented of the out of equilibrium dynamics of an infinite system of self-gravitating points initially located on a randomly pertu…
Gravitational Dynamics of an Infinite Shuffled Lattice: Particle Coarse-grainings, Non-linear Clustering and the Continuum Limit
T. Baertschiger, M. Joyce, A. Gabrielli +1
We study the evolution under their self-gravity of infinite ``shuffled lattice'' particle distributions, focussing specifically on the comparison of this evolution with that of ``d…
Gravitational Dynamics of an Infinite Shuffled Lattice of Particles
Thierry Baertschiger, Michael Joyce, Andrea Gabrielli +1
We study, using numerical simulations, the dynamical evolution of self-gravitating point particles in static euclidean space, starting from a simple class of infinite ``shuffled la…
Force distribution in a randomly perturbed lattice of identical particles with pair interaction
A. Gabrielli, T. Baertschiger, M. Joyce +2
We study the statistics of the force felt by a particle in the class of spatially correlated distribution of identical point-like particles, interacting via a pair force (i…
Linear perturbative theory of the discrete cosmological N-body problem
B. Marcos, T. Baertschiger, M. Joyce +2
We present a perturbative treatment of the evolution under their mutual self-gravity of particles displaced off an infinite perfect lattice, both for a static space and for a homog…
