Abstract Event-chain Monte Carlo (ECMC) algorithms are fast irreversible Markov-chain Monte Carlo methods. Developed first in hard sphere systems [1], they rely on the breaking of the detailed balance condition to speed up the sampling with respect to their reversible counterparts. However, to insure the sampling of the right target distribution they need the property of ergodicity. I will present a proof of ergodicity (resp. connectivity) for bidimensional soft (resp. hard) sphere systems, casting the ECMC methods in the framework of Piecewise Deterministic Markov Processes [2].
