We consider the planar Ising model on bounded domains from a conformal invariance point of view. We are interested in the scaling limit of the model at critical temperature. Physics theories, notably Conformal Field Theory, predict the existence of two conformal local fields describing the model in the continuum: the spin and the energy density.

At the Paul Scherrer Institute, Switzerland, we have recently measured the 2S-2P transition frequency (Lamb shift) in muonic hydrogen with 15 ppm precision by means of laser spectroscopy. From this measurement we have determined the rms charge radius of the proton.

Tue, Oct 26, 2010, 4:30 pm to Sun, Sep 26, 2010, 6:30 pm
Trace formulas for d-regular graphs are derived and used to express the spectral density in terms of the periodic walks on the graphs under consideration. The trace formulas depend on a parameter (w) which can be tuned continuously to assign different weights to different periodic orbit contributions.

Given a large set of discrete variables, and some constraints between them, is there a way to choose the variables so that all constraints are satisfied?This "satisfiability" problem is one of the most fundamental complex optimization problems. It also has very concrete applications, for instance in computer chip testing or in error correcting...
