Introduction to rapidly evolving parts of statistical physics. Stochastic thermodynamics studies energy transport and transformation processes on micro-scale of cells and even quantum systems. Active matter theory describes systems composed of non-equilibrium ``molecules’’ such as bacteria, insects, or birds.

1) Stochastic dynamics: Introduction to random processes. Basics of stochastic description – stochastic trajectories (Langevin equation, simulations) vs. ensemble description (master equations). Methods of solution.

2) Stochastic thermodynamics: Consistent thermodynamic descriptions (fluctuation-dissipation theorem, detailed balance condition). Definitions of heat, work, and entropy for individual trajectories of stochastic processes. Fluctuation theorems, thermodynamic uncertainty relations, and their consequences.

3) Active matter: Basics of wet active matter and its hydrodynamic description. Dry active matter – active Brownian particles, active Ornstein–Uhlenbeck process, Vicsek model. Basic solutions and results.
