Nonequilibrium statistical mechanics is a research area focused on the microscopic foundations and emergent behavior of systems driven away from thermodynamic equilibrium by external forces, gradients, or time-dependent protocols. It extends equilibrium statistical mechanics by analyzing transport processes, relaxation dynamics, fluctuation–dissipation relations, and entropy production in classical and quantum many-body systems. The field encompasses linear and nonlinear response theory, fluctuation theorems, large deviation theory, and stochastic thermodynamics, providing rigorous frameworks to quantify irreversibility, work, heat, and efficiency in driven systems ranging from molecular-scale engines and soft matter to plasmas and complex networks.
A study led by Professor Ginestra Bianconi from Queen Mary University of London, in collaboration with international researchers, has unveiled a transformative framework for understanding complex systems.

In a new Nature Communications study, scientists have demonstrated the quantum version of the strong Mpemba effect (sME) in a single trapped ion system.
Two systems exist in thermal equilibrium if no heat passes between them. Computers, which consume energy and give off heat as they process information, operate far from thermal equilibrium. Were they to stop consuming energy—say ...

A team of scientists have invented a technique to determine the dynamics of microscopic interacting particles by using image recognition to count the number of particles in an imaginary box. By changing the size of the observation ...
A new study has uncovered the universal dynamics far from equilibrium in randomly interacting spin models, thereby complementing the well-established universality in low-energy equilibrium physics. The study, recently published ...

The Kibble–Zurek (KZ) mechanism is a theoretical framework introduced by physicists Tom Kibble and Wojciech Zurek. This framework essentially describes the formation of topological defects while systems undergo non-equilibrium ...
A dissipative time crystal is a phase of matter characterized by periodic oscillations over time, while a system is dissipating energy. In contrast with conventional time crystals, which can also occur in closed systems with ...
