(A) Colloquium

Monte Carlo Simulations of Complex Physical Systems
　

Abstract:

The talk gives an overview of recent large-scale
computer simulations using Monte Carlo methods. The
use of cluster algorithms and generalised ensemble
methodologies in combination with finite-size scaling
analyses will be illustrated with examples from
disordered ferromagnets, random graphs and lattices,
spin glasses and protein folding.
　

(B) Seminar

"Optimal Paths" through Computer Simulations

Abstract:

The main emphasis of this talk will be on general
questions of computer simulations such as the choice
of update algorithms in Monte Carlo studies depending on
the problem at hand. Next autocorrelation times and the
resulting statistical errors will be discussed. Equally
important is the choice of suitable observables. Their
behavior in temperature and finite-size scaling studies
will be discussed and illustrated with a few selected
examples.
