Relativistic Wavepackets in Classically Chaotic Quantum Cosmological Billiards
Michael Koehn
Close to a spacelike singularity, pure gravity and supergravity in four to eleven spacetime dimensions admit a cosmological billiard description based on hyperbolic Kac-Moody group…

Supersymmetric quantum cosmological billiards
Axel Kleinschmidt, Michael Koehn, Hermann Nicolai
D=11 Supergravity near a space-like singularity admits a cosmological billiard description based on the hyperbolic Kac-Moody group E10. The quantization of this system via the supe…
