Statistical Physics: Transport Theory
Head of Research Group:
Prof. Dr. Siegfried Hess
Properties und Phenomena
which are investigated theoretically are:
- thermodynamic properties
- internal energy, pressure, shear modulus, ...
- transport coefficients
- viscosity, thermal conductivity, diffusion coefficients,
...
- rheology: flow properties
- non-Newtonian viscosity,
normal pressure differences
- plastic flow behaviors
- solid-solid friction properties
- diffusion controlled chemical reaction rates
- coupling of various transport processes
- relaxation processes
- hydrodynamic relaxation and relaxation of non-conserved quantities
e.g. stress relaxation
- dynamics of molecular orientation
- alignment phenomena
- optical properties
- e.g. line broadening, induced birefringence
- dielectric and ferro-electrical properties
- non-equilibrium distribution functions
- velocity distribution, pair correlation function,
orientation distribution
- structure und structure formation
- static and dynamic structure factors
- dynamic processes near phase transitions
- and the effect of external influences, e.g.
gas-liquid, liquid-solid, isotropic-nematic, smectic A-C* phase
transitions;
unified description of several phases.
- boundary and surface effects
- e.g. free surfaces, gases and liquids in contact with
rigid walls, boundary orientation
