Lagrangian formalism of gravity in the Randall-Sundrum model
Petter Callin, Finn Ravndal
We derive the effective Lagrangian of the physical four-dimensional fields in the Randall-Sundrum (RS) model, and use this to calculate the Newtonian gravitational potential betwee…
Scalar Field Fluctuations between Parallel Plates
Konrad Tywoniuk, Finn Ravndal
Quantum fluctuations of a scalar field and its derivatives are calculated when the field is confined between two parallel plates satisfying Dirichlet or Neumann boundary conditions…
The CMB spectrum in Cardassian models
Tomi Koivisto, Hannu Kurki-Suonio, Finn Ravndal
The dark energy in the Universe is described in the context of modified Friedmann equations as a fluid parameterized by the density of dark matter and undergoing an adiabatic expan…
Scalar Gravitation and Extra Dimensions
Finn Ravndal
Gunnar Nordstrom constructed the first relativistic theory of gravitation formulated in terms of interactions with a scalar field. It was an important precursor to Einstein's gener…
Higher order corrections to the Newtonian potential in the Randall-Sundrum model
Petter Callin, Finn Ravndal
The general formalism for calculating the Newtonian potential in fine-tuned or critical Randall-Sundrum braneworlds is outlined. It is based on using the full tensor structure of t…
