Joint Dept. of Mathematics and CMSA Random Matrix and Probability Theory Seminar: Free energy asymptotics of the quantum Heisenberg spin chain
Marcin Napiórkowski - University of Warsaw
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. Based on joint work with Robert Seiringer.
