Nature Physics Insight – Non-equilibrium physics


Efforts to probe the physics of systems removed from equilibrium date back to Maxwell himself. But recent progress has renewed interest in the endeavour — a trend highlighted by this Insight, collecting key advances from across the research spectrum.

Our framework for understanding non-equilibrium behaviour is yet to match the simplicity and power of equilibrium statistical physics. But recent theoretical and experimental advances reveal key principles that unify seemingly unrelated topics.

The other QFT pp108 – 110

Peter Hänggi & Peter Talkner

Fluctuation theorems go beyond the linear response regime to describe systems far from equilibrium. But what happens to these theorems when we enter the quantum realm? The answers, it seems, are now coming thick and fast.

Progress Article

Active gel physics pp110 – 117

J. Prost, F. Jülicher & J-F. Joanny

doi:10.1038/nphys3224

Equilibrium physics is ill-equipped to explain all of life's subtleties, largely because living systems are out of equilibrium. Attempts to overcome this problem have given rise to a lively field of research—and some surprising biological findings.

Towards quantum thermodynamics in electronic circuits pp118 – 123

Jukka P. Pekola

doi:10.1038/nphys3169

Experiments probing non-equilibrium processes have so far been tailored largely to classical systems. The endeavour to extend our understanding into the quantum realm is finding traction in studies of electronic circuits at sub-kelvin temperatures.

Quantum many-body systems out of equilibrium pp124 – 130

J. Eisert, M. Friesdorf & C. Gogolin

doi:10.1038/nphys3215

Statistical mechanics is adept at describing the equilibria of quantum many-body systems. But drive these systems out of equilibrium, and the physics is far from clear. Recent advances have broken new ground in probing these equilibration processes.

Thermodynamics of information pp131 – 139

Juan M. R. Parrondo, Jordan M. Horowitz & Takahiro Sagawa

doi:10.1038/nphys3230

The task of integrating information into the framework of thermodynamics dates back to Maxwell and his infamous demon. Recent advances have made these ideas rigorous—and brought them into the laboratory.
