Relativistic diffusing particles, entropy and varying cosmological constants
Z. Haba
We discuss Einstein equations with a non-conserved energy-momentum . The energy-momentum tensor on the right hand side of Einstein equations is expressed i…
Varying Newton constant, entropy and the black hole evaporation law
Julia Haba, Zbigniew Haba
In Einstein equations we represent the energy-momentum tensor as the one ( ) of a fluid plus the cosmological term. We consider time-dependent Newton ``constant" , the c…
Schrödinger evolution of a scalar field in Riemannian and pseudoRiemannian expanding metrics
Z. Haba
We study the quantum field theory (QFT) of a scalar field in the Schrödinger picture in the functional formulation. We derive a formula for the evolution kernel in a flat expanding…
Quantum scalar field propagator in a stochastic gravitational plane wave
Z. Haba
A stochastic metric can appear in classical as well as in quantum gravity. We show that if the linearized stochastic Gaussian gravitational plane wave has the frequency spectrum $ω…
