Topics in Quantum transport theory
The final essays of the study group:
Topics in Quantum transport theory
Aim: Ph.D. Course/study group in condensed
matter physics with an emphasis on Quantum transport theory.
Organizer: Mathias Lunde (Karsten Flensberg).
E-mail: lunan (at) fys.ku.dk
Phone: (+45) 353 20 385
ECTS Credits: 10 (4 punkter)
When: In the fall 2004 and spring 2005 (start: 7. September 2004). Tuesday from 14.15-17.
Place:
HCØ and MIC. Also
participant dependent.
Course description:
Every participant chooses a subject, which the person will go though at the black board (i.e. not (to much) power point) and be in charge of. This will take about 2 to 3 times depending of the participants number. One should not know anything about the subject chosen in order to keep the specified level and in order to learn something new. The idea of the course is to try to understand the basic content of the subject chosen, such as the basic mechanisms (basic physics), models and equations (formalism). It is meant to be a discussion, so the person in charge chooses some material (articles and/or chapters from book(s)), which all the other participants read. The four hours could (or maybe should) also contain some exercises. The senior staff are not suppose to give lectures,only to supervise.
Subjects covered:
1. Kondo effect with emphasis on poor mans scaling (A. Mathias Lunde).
2. Dynamical mean field theory (Dan Bohr).
1. Quantum hall effect (Thomas Frederiksen).
4. Density functional theory (Mikkel Strange).
5. Quantum monte carlo simulations (Christian Flindt).
