Quantum Dynamics of Mixmaster Universe

Mixmaster universe is an anisotropic cosmological model comprising the Friedmann model a special case. Towards the big-bang singularity the isotropy of space is dynamically unstable, thus the quantization of the isotropic models  alone appears to be insufficient to describe the earliest Universe. In my talk I will present the quantum version  of the Mixmaster universe obtained  by implementing affine coherent state quantization  combined with a Born-Oppenheimer-like adiabatic approximation, widely utilized in quantum molecular physics. The resolution of the classical singularity occurs by means of a repulsive potential generated by the quantization procedure.  The quantized anisotropic degrees of freedom behave as radiation energy density. The Friedmann-like lowest energy eigenstates of the system seem, in opposite of classical case, to be dynamically stable against small anisotropy perturbations.

W związku z pogrzebem prof Wilczyńskiego, który planowany jest na środę na godzinę 13 
(na wojskowych Powązkach) nasze seminarium rozpoczniemy godzinę wcześniej tj. o 11.15!
Serdecznie zapraszamy,

M. Kowal, W. Piechocki, L. Roszkowski, J. Skalski
