The Hartle-Hawking state for the Bianchi IX model in supergravity
R. Graham, H. Luckock
We solve the quantum constraints for homogeneous N=1 supergravity on 3-geometries with a Bianchi IX metric. Because these geometries admit Killing vectors with the same commutation…

Nicolai Maps for Quantum Cosmology
R. Graham, H. Luckock
We construct Nicolai maps for supersymmetric extensions of minisuperspace models. It is shown that Nicolai maps exist for only a very restricted set of states. In the models…

Transition from Poissonian to GOE level statistics in a modified Artin's billiard
A. Csordás, R. Graham, P. Szépfalusy +1
One wall of Artin's billiard on the Poincaré half plane is replaced by a one-parameter () family of nongeodetic walls. A brief description of the classical phase space of this…
