Research Activities

My research work lies within the scope of statistical physics and is devoted in particular to the study of non-equilibrium systems.

A word on the problematic...

the statistical properties of systems at thermal equilibrium are generally well understood theoretically, it is far from being the case out-of-equilibrium. This is all the more deceptive than equilibrium is rather the exception than the rule in nature. The theoretical understanding of non-equilibrium systems and in particular of non-equilibrium critical phenomena appears as a one of the major challenges of statistical mechanics nowadays. Making progress requires the development of new theoretical tools. In this respect, the framework of field theory, and more specifically non-perturbative renormalization group methods (initially developed in the nineties for high-energy physics) stand as promising candidates to investigate the rich physics of non-equilibrium systems and they are part of my field of expertise.

My main research interests :

  • Reaction-diffusion processes :

 through different models such as directed percolation or branhing and annihilating random walks.
collaborators : B. Delamotte, H. Chaté, N. Wschebor, H. Hilhorst, I. Dornic, M. Munoz.

  • Interface growth and roughening transition

through the study of the Kardar-Parisi-Zhang equation.
collaborators : M.A. Moore, B. Delamotte, H. Chaté, N. Wschebor, T. Kloss.

  • Fully developed isotropic and homogeneous turbulence

through the study of the Navier-Stokes equation.
collaborators : B. Delamotte, N. Wschebor.

  •  Theoretical studies of the non-perturbative renormalisation group

focusing on the properties of the derivative expansion on the example of the three dimensional Ising model.
collaborators : B. Delamotte, D. Mouhanna, J. Vidal
