On phase-space singular surfaces in gravity
Dražen Glavan, David M. J. Vokrouhlický
We perform a Hamiltonian constraint analysis of metric gravity in the Jordan frame and show that the regular constraint classification degenerates on singular phase-space su…
On the Bondi accretion of a self-interacting complex scalar field
Dražen Glavan, Alexander Vikman, Tom Zlosnik
Scalar fields with a global U(1) symmetry often appear in cosmology and astrophysics. We study the spherically-symmetric, stationary accretion of such a classical field onto a Schw…
Measurements in stochastic gravity and thermal variance
Markus B. Fröb, Dražen Glavan, Paolo Meda
We analyze the thermal fluctuations of a free, conformally invariant, Maxwell quantum field (photon) interacting with a cosmological background spacetime, in the framework of quant…
Late-time quantum backreaction of a very light nonminimally coupled scalar
Dražen Glavan, Tomislav Prokopec, Tomo Takahashi
We investigate the backreaction of the quantum fluctuations of a very light () nonminimally coupled spectator scalar field on the expansion dynamic…
Nonminimal coupling and the cosmological constant problem
Dražen Glavan, Tomislav Prokopec
We consider a universe with a positive effective cosmological constant and a nonminimally coupled scalar field. When the coupling constant is negative, the scalar field exhibits li…
