Non-adiabatic transitions in a massless scalar field
Non-adiabatic transitions massless scalar field Mathematical Physics
2012/4/17
We consider the dynamics of a massless scalar field with time-dependent sources in the adiabatic limit. This is an example of an adiabatic problem without spectral gap. The main goal of our paper is t...
Scalar Field in Non-commutative Curved Space time
Scalar Field Non-commutative Curved Space time
2010/12/24
We will study the theory of scalar field in non-commutative curved space time (NCCST) with a percussionist who has been found by Mebaraki. In this paper, the motion equation of the scalar field will ...
Scalar field reconstruction of power-law entropy-corrected holographic dark energy
Scalar field reconstruction power-law entropy-corrected holographic dark energy
2010/12/24
A so called "power-law entropy-corrected holographic dark energy" (PLECHDE) was recently proposed to explain the dark energy dominated universe. This model is based on the power-law corrections to bl...
Stability and Quasinormal Modes of Black holes in Tensor-Vector-Scalar theory: Scalar Field Perturbations
Stability Quasinormal Modes of Black holes Tensor-Vector-Scalar theory Scalar Field Perturbations
2010/12/20
The imminent detection of gravitational waves will trigger precision tests of gravity through
observations of quasinormal ringing of black holes. While General Relativity predicts just two po-larizat...
Scalar field in nuclear matter: the roles of spontaneous chiral symmetry breaking and nucleon structure
nuclear matter roles of spontaneous chiral symmetry breaking nucleon structure
2011/1/6
Chiral theories with spontaneous symmetry breaking such as the Nambu-Jona-Lasinio (NJL)
model lead to the existence of a scalar mode. We present in a detailed manner how the corresponding low momentu...
Cosmology of an asymptotically free scalar field with spontaneous symmetry breaking
asymptotically free scalar spontaneous symmetry breaking
2010/12/20
We solve Einstein’s equation with Robertson-Walker metric as an initial-value problem, using as the source of gravity a Halpern-Huang real scalar field, which was derived from renormalization-group an...
Unified Dark Matter scalar field models with fast transition
Unified Dark Matter scalar field fast transition
2010/12/22
We investigate the general properties of Unified Dark Matter (UDM) scalar
field models with Lagrangians with a non-canonical kinetic term, looking specifically for
models that can produce a fast tra...
Boltzmann Equation for Relativistic Neutral Scalar Field in Non-equilibrium Thermo Field Dynamics
Boltzmann Equation Relativistic Neutral Scalar Field
2010/12/22
A relativistic neutral scalar field is investigated on the basis of the Schwinger-Dyson equation in the non-equilibrium thermo field dynamics. A time evolution equation for a distribution function is...
In this paper we analyze perturbatively a g phi^4 classical field theory with and without temperature. In order to do that, we make use of a path-integral approach developed some time ago for classic...
Consistency of Equations for the Single Scalar Field Case in Second-order Gauge-invariant Cosmological Perturbation Theory
Single Scalar Field Case Cosmological Perturbation Theory
2010/3/18
We derived the second-order perturbations of the Einstein equations and the Klein-Gordon equation for a generic situation in terms of gauge-invariant variables. The consistency of all the equations is...
Polymer quantization of the free scalar field and its classical limit
free scalar field Polymer quantization classical limit
2010/3/18
Building on prior work, a generally covariant reformulation of free scalar field theory on the flat Lorentzian cylinder is quantized using Loop Quantum Gravity (LQG) type `polymer' representations. Th...
Fock quantization of a scalar field with time dependent mass on the three-sphere: unitarity and uniqueness
Fock quantization scalar field unitarity
2010/3/17
We study the Fock description of a quantum free field on the three-sphere with a mass that depends explicitly on time, also interpretable as an explicitly time dependent quadratic potential. We show t...

Attractors in Dark Energy Models with Born-Infeld Scalar Field
Dark Energy Models Born-Infeld Scalar Field
2010/10/15
We derive, in the large scale limit, analytical solutions for a dark energy model described by the Born-Infeld field plus a perfect fluid, both for homogeneous background and first order perturbations...
