Dr. Elsen Tjhung – Stochastic thermodynamics of active matter
Thermodynamics has been very successful to study the engines inside our cars, airplanes and power plants. However, what if the engines are very small, e.g. molecular engines inside biological cells? In this regime, thermal fluctuations become important and we need to use the new theory of stochastic thermodynamics. In this talk I will give brief introduction to stochastic thermodynamics and its applications to active matter. In active matter, the particles consumes fuel in order to self-propel. At large scale a large number of self-propelled particles can phase separate. In this talk I will also discuss how we can apply stochastic thermodynamics to active phase separation.
