NBI Journal Club

Spring 2002

Condensed Matter Theory

Old schedules: Fall 99, Spring 2000, Fall 2001

Organizers: Brian M Andersen, Vadim Cheianov

NOTE: 1) The people giving the talks (except for students) are encouraged NOT to present papers directly related to their own research!
NOTE: 2) Use of blackboard is preferred since it helps to control the pace of the presentation! However, experimental graphs etc are probably best presented on the projector!
