Michael Sarrazin

Michael Sarrazin is a Professor of Physics at Université de Bourgogne-Franche-Comté, France, where he conducts research at the Institut UTINAM. His primary affiliations include the Department of Physics within the Faculty of Sciences, and he has established himself as a leading researcher in theoretical and experimental physics related to braneworld models and neutron phenomena.

Dr. Sarrazin earned his Ph.D. in Physics from Université de Franche-Comté in 2002, followed by a Habilitation (HDR) from Université de Bourgogne-Franche-Comté in 2016, which granted him accreditation to supervise research. His academic journey reflects a deep commitment to advancing our understanding of fundamental physics through both theoretical and experimental approaches.

His research focuses on the intersection of high-energy physics and condensed matter systems, with particular emphasis on braneworld phenomenology in physics beyond the Standard Model and electrodynamics in low-dimensional systems. Sarrazin's work explores how concepts from string theory and extra dimensions might manifest in observable phenomena, particularly through neutron physics experiments. His research program spans from theoretical investigations of braneworld scenarios to practical applications in graphene and other two-dimensional materials.

Analysis of his 15 most recent publications reveals a consistent research trajectory centered on testing braneworld hypotheses through neutron physics experiments. His work demonstrates how neutron disappearance/reappearance phenomena could provide evidence for hidden braneworlds, with experimental approaches ranging from reactor neutrino experiments to specialized low-noise setups like the MURMUR experiment. More recently, his research has expanded to include connections between braneworld models and cosmological phenomena like baryogenesis.

Dr. Sarrazin has led and participated in numerous significant research projects, including MURMUR (2016-2021), CLEANOPTIC (2011-2015), and PHENO (2007-2009). His work has been supported by substantial research funding focused on exploring the boundaries of fundamental physics through innovative experimental designs and theoretical frameworks.

His laboratory work centers around the development of sensitive experimental apparatus for detecting potential signatures of braneworld physics, particularly through neutron oscillation phenomena. The MURMUR experiment represents his most recent major experimental effort, designed as a high-sensitivity, low-noise platform for detecting neutron-hidden neutron transitions. His research group maintains strong collaborations with international partners across Europe, reflecting the global significance of his work in fundamental physics.
