Description of research, present lines and highlights from last years
Our group is concerned with development of a thermodynamically founded theory of transport, non-equilibrium thermodynamics. There are several lines of research described below by the four following headings.
1. Non-equilibrium thermodynamics for surfaces
Together with Signe Kjelstrup I have developed the theory of non-equilibrium thermodynamics for surfaces to a stage where a book will appear on World Scientific in 2008 as Vol.16 in their Series on Statistical Mechanics.
The book is a synthesis of many of the earlier works and works listed below. A non-equilibrium generalization of the square gradient model for the liquid-vapor interface due to van der Waals has been given which makes it possible to describe evaporation and condensation. The validity of the local equilibrium hypothesis for the Gibbs excess densities of the non-equilibrium surface was verified the transfer coefficients for heat and mass transfer through the surface were calculated. Integral relations for these transfer coefficients were derived. This is described in no. 194 and is one of the highlights of this work.

2. Non-equilibrium molecular dynamics
Molecular dynamics simulations are used to obtain the equilibrium properties as well as the transfer coefficients for the surface. The validity of the local equilibrium hypothesis for the Gibbs excess densities of the non-equilibrium surface has been verified in these simulations. The transfer coefficients for heat and mass transfer were calculated.
The validity of the integral relations was verified. New transfer coefficients were calculated in this manner. A highlight is no. 190 (which gave a prize to the student from Int. Soc. of Thermodynamics) which verified the validity of the Onsager relations for the surface..

3. Mesoscopic non-equilibrium thermodynamics
A new line of research which will be followed-up in the future, is mesoscopic non-equilibrium thermodynamics.
This theoretical development will be particularly interesting for analysis of biological transport processes, molecular motors, systems biology. A highlight is no. 185.

4. The response of double layers on applied electric fields
In this work the double layer is treated using the extension of the general method developed by Gibbs using a time dependent excess polarization. Earlier results could in this way be obtained in a simpler manner. For the dielectric enhancement of colloidal solutions analytic expressions could be given. A systematic comparison with results using available computer software is now being made.

5. The collective behavior of self-propelling particles
The dynamics of systems consisting of self-propelling particles is of great interest because of the phenomenon of the emergence of ordered motion. Examples of such systems are flocks of birds and schools of fishes. Much in the description of this transition is not yet understood. We developed a hydrodynamic model and were able to reproduce some of the results from the more usual discrete models. The non-equilibrium behavior is now studied.
