THE SEMINAR

THEORY OF DUALITY

DEPARTMENT OF MATHEMATICAL METHODS IN PHYSICS



On the 13th of October 2016, at 10:15 a.m.

Marcin Napiórkowski (KMMF WFUW)

will give a talk on

"A mathematical-physics perspective on spin-wave theory"

Abstract
Spin-wave theory suggests that low-temperature properties of the Heisenberg model can be described in terms of noninteracting quasiparticles called magnons. In my talk, I will review the basic concepts and predictions of spin-wave approximation and report on recent rigorous results in that direction.

The seminar takes place on Thursdays from 10:15 a.m. to 12:00 in the room 2.23 of the main building of the Faculty of Physics (the 2nd floor), Pasteur Str. 5, Warszawa.
