Path Integral Quantization of Cosmological Perturbations
S. Anderegg, V. Mukhanov
We derive the first order canonical formulation of cosmological perturbation theory in a Universe filled by a few scalar fields. This theory is quantized via well-defined Hamiltoni…

On 4D-Hawing Radiation from Effective Action
V. Mukhanov, A. Wipf, A. Zelnikov
We determine the -waves contribution of a scalar field to the four dimensional effective action for arbitrary spherically symmetric external gravitational fields. The result is…

On the Symmetries of Hamiltonian Systems
V. Mukhanov, A. Wipf
In this paper we show how the well-know local symmetries of Lagrangeans systems, and in particular the diffeomorphism invariance, emerge in the Hamiltonian formulation. We show tha…
