Fractional Scalar Field Cosmology

Fractal and Fractional
Considering the Friedmann–Lemaître–Robertson–Walker (FLRW) metric and the Einstein scalar field system as an underlying gravitational model to construct fractional cosmological models has interesting implications in both classical and quantum regimes ...

Renormalization for a Scalar Field in an External Scalar Potential [PDF]

Symmetry, 2018
The Pauli–Villars regularization procedure confirms and sharpens the conclusions reached previously by covariant point splitting. The divergences in the stress tensor of a quantized scalar field interacting with a static scalar potential are isolated into a three-parameter local, covariant functional of the background potential.

Differences between scalar field and scalar density field solutions [PDF]

Canadian Journal of Physics, 2012
Differences between scalar field and scalar density solutions are explored using a Robertson–Walker (RW) metric, and a nonrelativistic Hamiltonian is derived for a scalar density field in the post-newtonian approximation. The results are compared with those of a scalar field.
