Tema:  Renormalization of Hamiltonians: Method and Examples
Prednasejici: Dr. A. Mielke (Universita Heidelberg)

Abstrakt:
Using continuous unitary transformations, it is possible to
obtain flow equations for Hamiltonians. Such a method is
useful e.g. for problems in condensed matter physics
or in high energy physics for the description of bound states.
It has been applied to dissipative quantum systems, to problems
of interacting electrons or to electrons interacting with phonons
in condensed matter physics, and as well to bound state problems
in QCD. We will give an introduction to the method and we will
show how this method is applied to the electron-phonon problem.
