We prove that the system converges exponentially to the unique Boltzmann-Gibbs invariant measure under a weighted total variation distance. The proof relies on a novel construction of Lyapunov function for the Coulomb system.", "revisions": [ { "version": "v1", "updated": "2019-02-02T01:00:04.000Z" } ], "analyses": { "keywords": [ "langevin dynamics", "coulomb interactions", "geometric ergodicity", "unique boltzmann-gibbs invariant measure", "second order system" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
