Tristan Benoist

Tristan Benoist

I am a researcher (CR CNRS) in mathematical physics in the probability team of Toulouse Mathematics Institute (IMT). I am also an associate researcher at neighboring Theoretical Physics Laboratory (LPT).

I am mainly interested in the mathematics of quantum system thermodynamics. I focus on definitions of thermodynamic quantities and their fluctuations, and study related questions in probability.

With Cécilia Lancien, Ion Nechita and Clément Pellegrini, we organize the IMT-LPT mathematical physics seminar. The schedule is available on the IMT website and the LPT website.

I am the coordinator of ANR project “Quantum Trajectories (QTraj)”. Some postdoctoral positions and internships will be available. Contact me for information. I am also a member of ANR project ESQUISSE.

Fall school on Quantum Trajectories and related topics (Toulouse, 18-22 Oct. 2021)

Internships and Ph.Ds

Here is a list of examples of subjects of masters internships I can propose. They can all be continued into a Ph.D. or constitute the starting point of a Ph.D.

If you have any inquiry or idea of subject related to my research please feel free to contact me.

(no hierarchy is meant in the order of the list)
