The semiclassical many body density of states: Progress in the treatment of the smooth part — •Quirin Hummel, Juan Diego Urbina, Jack Kuipers, and Klaus Richter — Universität Regensburg, Germany

For single particle billiard systems, the smooth part of the density of states (DOS) in a semiclassical approximation is known as the Weyl expansion. We study a corresponding expansion for the smooth part of the many body DOS in systems of identical particles. We show that the treatment of exchange symmetry already has a strong effect. As an extension we present progress in including additional effects like physical boundaries. The possibility of including short range interactions among particles is discussed.
