Quantized Scalar Fields Under the Influence of Moving Mirrors and Anisotropic Curved Spacetime
- Physics
- 2011
MICHAEL R.R. GOOD: Quantized Scalar Fields Under the Influence of Moving Mirrors and Anisotropic Curved Spacetime. (Under the direction of Charles R. Evans and Paul R. Anderson.) This thesis develops…
What Do Detectors Detect
- Physics
- 2016
By a detector, one has in mind a point particle with internal energy levels, which when set in motion on a generic trajectory can get excited due to its interaction with a quantum field. Detectors…
Theory of superconductivity of gravitation and the dark matter enigma
- Physics
- 2011
In this article, the question of the nature of cold dark matter is approached from a new angle. By invoking the Cauchy problem of relativity it is shown how, under very precise astrophysical…
Perturbative Quantum Gravity and Yang-Mills Theories in de Sitter Spacetime
- Physics
- 2009
This thesis consists of three parts. In the first part we review the quantization of Yang-Mills theories and perturbative quantum gravity in curved spacetime. In the second part we calculate the…
P o S ( Q GP h ) 0 1 5 Extended Gravity : Theory and Phenomenology
- Physics
- 2007
Extended Theories of Gravity can be related to several quant um gravity approaches and unification schemes. They have recently attracted a lot of interest as alternative candidates to explain the…
Casimir energy-momentum tensor for a quantized bulk scalar field in the geometry of two curved branes on Friedmann-Robertson-Walker background
- Physics
- 2016
In a previous work [S. Rahbardehghan and H. Pejhan, Phys. Lett. B 750, 627 (2015)], we considered a simple brane-world model: a single four-dimensional brane embedded in a five-dimensional de Sitter…
Local Covariance, Renormalization Ambiguity, and Local Thermal Equilibrium in Cosmology
- Physics
- 2012
This article reviews some aspects of local covariance and of the ambiguities and anomalies involved in the definition of the stressenergy tensor of quantum field theory in curved spacetime. Then, a…
Momentum of cosmological acoustic field
- Physics
- 2011
The acoustic spacetime corresponding to perturbed Friedman-Lemaitre-Robertson-Walker universe inherit the space isometries from the original FLRW model, but essentially differs in dynamics. The scale…
Possible Observation of Phase Transitions in Two-Nucleon Systems
- Physics
- 2015
A simple condition of deep cooling for observation of phase t ransitions in compressed fewnucleon systems was recently proposed. Here we have checked it using data obtained in the first physical…
On the Removal of Infinities from Divergent Series
- Philosophy
- 2015
The consequences of adopting other definitions of the concepts of sum and convergence of a series are discussed in the light of historical and epistemological contexts. We show that some divergent…
