Local Universality of Repulsive Particle Systems and Random Matrices    [PDF]

F. Götze, M. Venker

We study local correlations of certain interacting particle systems on the real line which show repulsion similar to eigenvalues of random Hermitian matrices. More precisely the pair interaction differs from the GUE-eigenvalue interaction by a smooth function. Although the new interaction does not seem to have a spectral or determinantal representation, the local correlations in the bulk coincide in the limit of infinitely many particles with those known from random Hermitian matrices, in particular they can be expressed as determinants of the so-called sine kernel. These results may provide an explanation for the appearance of sine kernel correlation statistics in a number of situations which do not have an obvious interpretation in terms of random matrices.
