Response of a canonical ensemble of quantum oscillators to a random metric
Z. Haba
We calculate the susceptibility of a canonical ensemble of quantum oscillators to the singular random metric. If the covariance of the metric is $\vert {\bf x}-{\bf x}^{\prime}\ver…
Quantum state evolution in an environment of cosmological perturbations
Z. Haba
We study the pure and thermal states of quantized scalar and tensor perturbations in various epochs of Universe evolution. We calculate the density matrix of non-relativistic parti…
The impact of a random metric upon a diffusing particle
Z. Haba
We show that if the singularity of the quantized gravity propagator is then the mean value of the fourth power of the distance achieved in time by a…
State-dependent graviton noise in the equation of geodesic deviation
Z. Haba
We consider an equation of the geodesic deviation appearing in the problem of gravitational wave detection in an environment of gravitons. We investigate a state-dependent graviton…
Semi-classical Einstein equations:descend to the ground state
Zbigniew Haba
The time-dependent cosmological term arises from the energy-momentum tensor calculated in a state different from the ground state. We discuss the expectation value of the energy-mo…
Power spectrum of stochastic wave and diffusion equations in the warm inflation models
Z. Haba
We discuss dissipative stochastic wave and diffusion equations resulting from an interaction of the inflaton with an environment in an external expanding metric. We show that a dif…
