Applied nonequilibrium statistical mechanics

Theory and modelling -- tribology, surface science, transport properties, nonlinear dynamics, condensed matter

The group's aim is to develop new, general, models for transport of matter, energy, and momentum, and relate it to microscopic nonlinear dynamics. We currently focus on two types of systems:

molecules and nanoscale objects on surfaces, especially in the context of friction, and
gases and liquids of various levels of complexity.

We employ computational as well as analytical methods to solve applied and fundamental problems. We collaborate with experimental as well as theoretical researchers from a wide variety of fields, ranging from chemical engineering to mathematical physics. More details below.
