Power functional theory is a new approach that makes it possible to describe precisely the dynamics of many-particle systems over time. Physicists at the University of Bayreuth are among the ...

Statistical physics and thermodynamics provide a framework for relating the behaviour of microscopic particles to the macroscopic properties of a system. Thermodynamics casts these macroscopic, or ...

Nonlinear optical materials such as silicon can be used to make on-chip devices that break dynamic reciprocity. (Courtesy: K Xia) A new method for making devices that act like a “one-way street” for ...
