Non-equilibrium Statistical Mechanics

Non-equilibrium statistical mechanics is the branch of statistical mechanics that studies systems not in a state of equilibrium, meaning they are experiencing changes over time, like heat flow or chemical reactions. While equilibrium systems tend to settle into stable patterns, non-equilibrium systems can behave unpredictably. This field uses statistics to understand the properties and behaviors of these dynamic systems, helping us analyze how they evolve, respond to external forces, and reach new states. It plays a crucial role in various disciplines, including biology, chemistry, and physics, where real-world processes often deviate from perfect equilibrium.
