Master/graduate course 712:

Topics in Physics of Complex Systems

Selected topics in the research areas of the ``Complex Systems
Group  ( CATS etc)'' at the Niels Bohr Institute,
Blegdamsvej. The course can be followed by students at 4-5'th year
and by PhD students. The course is ideal for student who plan to
write their thesis within complex systems and bio-complexity.
The topics that will be covered are:
Burgers equation, shell models for turbulence, scaling analysis
for Navier-Stokes equations, non-equilibrium statistical mechanics,
the motion and scaling behavior of interfaces, hydrodynamics
instabilities, self-organized critical behavior, patterns,
ripple formation in sand, proteins in cells, diffusion in biological membranes, etc.

Students should preferably have taken the following courses:
Fysik 222/Dynamiske Systemer  Fysik222/Dynamiske Systemer  , Statistisk Mekanik, evt. Hydrodynamik

Time and place: Niels Bohr Institutet, Blegdamsvej 17, Aud. D,
                Thursdays 13.15 - 15. First time: Week 37.
                Two hours exercises per week.

Exam:  Oral. About 12-15 questions from a curriculum defined
       by material (notes, papers, book chapters) handed out
       by the teachers.
