-* Manon MICHEL defended her thesis, entitled "Irreversible Markov Chains by the Factorized Metropolis Filter: Algorithms and Applications in Particle Systems and Spin Models" on 17 October 2016. The jury was composed of: Marjolein DIJKSTRA (Universiteit Utrecht, Netherlands), Eric MOULINES (Ecole Polytechnique, France), Anthony MAGGS (ESPCI, France), Cristopher MOORE (Santa Fe Institute), Francesco ZAMPONI (ENS, France), and myself. Congratulations!+* Nicolas Noirault joined our group from 25 May 2021 through 20 July 2021, during his first-year master internship at the University of Paris. With his bachelor's degree in Mathematics and in Physics from the University of Cergy, he was brillantly qualified to work on a famous paper by mathematician K. Böröczky on locally stable disk packings, that we connected to modern developments in Markov chains. In collaboration with P. Höllmer, B. Li, and A. C. Maggs, we submitted [[Hoellmer_Noirault_Li_Maggs_Krauth_2021|our paper "Sparse hard-disk packings and local Markov chains"]] to arXiv in September 2021, only four months (!) after the beginning of the 'stage de M1'.

Philipp holds a special scholarship of the Bonn-Cologne Graduate School of Physics and Astronomy Honors Branch, which rendered this visit possible. At the moment, we heavily rely on his physical insights, and his expert skills in cutting-edge computational problems.
 +* Michael F. Faulkner [mailto:michael.faulkner@bristol.ac.uk mail], EPSRC research fellow at the H. H. Wills Physics Laboratory, University of Bristol, UK, is again visiting us for two weeks (16 July 2018 - 27 July 2018), to continue our [[Faulkner_Qin_Maggs_Krauth_2018|exciting work on Coulomb systems]].
