Laura Guislain receives the 2025 Academic Thesis Prize of Université Grenoble Alpes

Defended on July 10, 2024 at LIPhy, the thesis focuses on systems held out of equilibrium by forcing, which often exhibit a rich phenomenology. Examples include the synchronisation transition, in which oscillators of different frequencies begin to oscillate in phase if their interactions are sufficiently strong, or the appearance of oscillations in highly dissipative systems, such as chemical clocks (Belousov-Zhabotinsky reaction). Such systems are archetypes of non-equilibrium statistical physics, which has developed methodologies adapted to their study. In this thesis, theoretical tools were developed to study out-of-equilibrium phase transitions with the emergence of a limit cycle, in the case where the microscopic degrees of freedom are not constrained to oscillate as in standard studies of the synchronisation transition but can lead to a form of oscillation in certain regimes.
