Titel: | "The corner transfer matrix renormalization group method: series
expansions and applications" |
Vortragender: | Yao-ban Chan (Univ. Wien). |
Inhalt: |
The corner transfer matrix renormalization group method is a powerful
algorithm for evaluating physical quantities in statistical mechanical models.
It was developed by Nishino and Okunishi in 1996, and originates
from Baxter's corner transfer matrix equations and method devised in the
late 70s.The method has been applied to numerous models since its development,
but only numerically, while Baxter's original method was used to calculate
series expansions. In this talk, we give a detailed description of the
original CTM equations and the CTMRG method. Then we describe our adaptation
of this method which can calculate series expansions. We have applied this
method to several models --- of particular interest is the generating
function of self-avoiding polygons --- and we present our results.
