Galactic Halos and Black Holes in Non-Canonical Scalar Field Theories
Ratindranath Akhoury, Christopher S. Gauthier
We consider static spherically symmetric solutions of a general scalar field theory with non-standard kinetic energy coupled to gravity with a view to explain dark matter halos as…
A Kaluza-Klein Model with Spontaneous Symmetry Breaking: Light-Particle Effective Action and its Compactification Scale Dependence
Ratindranath Akhoury, Christopher S. Gauthier
We investigate decoupling of heavy Kaluza-Klein modes in an Abelian Higgs model with space-time topologies and $\mathbb{R}^{3,1} \times S^{1}/\mathb…
Propagation Constraints and Classical Solutions in K-essence Like Theories
Ratindranath Akhoury, Christopher S. Gauthier
We consider two examples of solutions of the equations of motion of scalar field theories with higher derivatives. These are the cosmology of the rolling tachyon and static spheric…
Decoupling of Heavy Kaluza-Klein Modes In Models With Five-Dimensional Scalar Fields
Ratindranath Akhoury, Christopher S. Gauthier
We investigate the decoupling of heavy Kaluza-Klein modes in theory and scalar QED with space-time topology . We calculate the effective acti…
Cosmology Quantized in Cosmic Time
Marvin Weinstein, Ratindranath Akhoury
This paper discusses the problem of inflation in the context of Friedmann-Robertson-Walker Cosmology. We show how, after a simple change of variables, to quantize the problem in a…
Quantized Cosmology II: de Sitter Space
Marvin Weinstein, Ratin Akhoury
This work applies the formalism developed in our earlier paper to de Sitter space. After exactly solving the relevant Heisenberg equations of motion we give a detailed discussion o…
