Sébastien Ott

Sébastien Ott is a Lecturer in the Department of Mathematics at École Polytechnique Fédérale de Lausanne (EPFL), affiliated with both the SB-SMA-SMA-ENS and SB-MATH-MATH-GE units. He contributes to teaching courses such as Probability and Statistics and Large Deviations, focusing on mathematical foundations of statistical physics.

Research interests centered on Statistical Mechanics and Probability Theory, particularly in systems like the Ising and Potts models. His work investigates critical phenomena, correlation decay, interface behavior, and large deviation principles. Articles often address topics such as Ornstein-Zernike asymptotics, phase transitions, and spatial mixing properties.

His publications reveal a focus on

• Ising/Potts model phase transitions
• Large deviations and fluctuation regimes
• Surface localization/delocalization
• Renormalization group applications
• Correlation length analyticity

with connections to mathematical physics and percolation theory.
