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
    • e.g. flow alignment
  • 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
