Abstract

We investigate the quantum statistical physics of a microscopic mean-field glass model in various approximations using the replica method and effective action methods from quantum field theory. We recover results from a semiclassical treatment and find relations to quantum spherical p-spin models.

Wir untersuchen die quantenstatistische Physik eines mikroskopischen Mean-Field Modells für Gläser mit Hilfe der Replica-Methode und der Theorie der Effektiven Wirkungen aus der Quantenfeldtheorie. Wir können bekannte Resultate aus einer semiklassischen Behandlung des Modells bestätigen und finden enge Beziehungen zu sphärischen Quanten-p-Spin Modellen.
