Dear All,
let me try and see whether it is easier to put an announcement here than to send the e-mail around.
August 8 (Wednesday), 14:00, Olga Shevchuk from University of Amsterdam will give a talk in Gerrit's room

Transfer matrix as powerful tool to solve the gapless XXZ model
Abstract:
Bethe Ansatz is widely used to describe
thermodynamic properties of certain one-dimensional quantum many-body
models. One such model is the gapless spin-1/2 anisotropic Heisenberg
chain with periodic boundary conditions. In my talk I
will start from some basic introduction to the Bethe Ansatz and proceed
with numerical method of solving Bethe equations of this model which is
based on exact diagonalization, transfer matrix, and polynomial-fitting.
In the end, I will show you some of the
results that was obtained by this method. The findings show that the
transfer matrix is able to describe all eigenstates of the system.
Olga is a candidate for a PhD position. I may also ask a couple of you to talk briefly to her.
Yaroslav
