Symmetry of the Klein-Gordon Equation under Disformal Transformations with Higher-Order Derivatives

Yurev Ivan Ross B. Carag, Allan L. Alinea

Scalar-Tensor theories extend General Relativity (GR) by including both a scalar field and a metric tensor in describing gravity. Although the matter sector is minimally coupled to…

On the KG-constrained general disformal transformation of the Einstein-Hilbert action

Allan L. Alinea, Joshwa DJ. Ordonez

Although with great successes in explaining phenomena and natural behaviour involving the Universe or a part thereof, the General Theory of Relativity is far from a complete theory…

On the KG-constrained Bekenstein's disformal transformation of the Einstein-Hilbert action

Allan L. Alinea, Joshwa DJ. Ordonez

Motivated by an inclination for symmetry and possible extension of the General Theory of Relativity within the framework of Scalar Theory, we investigate the Bekenstein's disformal…

Percolation of 'Civilisation' in a Homogeneous Isotropic Universe

Allan L. Alinea, Cedrix Jake C. Jadrin

In this work, we consider the spread of a 'civilisation' in an idealised homogeneous isotropic universe where all the planets of interest are habitable. Following a framework that…

Extending the symmetry of the massless Klein-Gordon equation under the general disformal transformation

Allan L. Alinea, Mark Ruel D. Chua

The Klein-Gordon equation, one of the most fundamental equations in field theory, is known to be not invariant under conformal transformation. However, its massless limit exhibits…

Cognitive Reflection Test and the Polarizing Force-Identification Questions in the FCI

Allan L. Alinea

The set of polarizing force-identification (PFI) questions in the FCI consists of six items all basically asking only one question: the set of forces acting on a given body. Althou…

On the Disformal Transformation of the Einstein-Hilbert Action

Allan L. Alinea

Disformal transformation is a generalisation of the well-known conformal transformation commonly elaborated in mainstream graduate texts in gravity (relativity) and modern cosmolog…

Transformation of Primordial Cosmological Perturbations Under the General Extended Disformal Transformation

Allan L. Alinea, Takahiro Kubota

Primordial cosmological perturbations are the seeds that were cultivated by inflation and the succeeding dynamical processes, eventually leading to the current Universe. In this wo…

Adiabatic regularization of power spectrum in nonminimally coupled general single-field inflation

Allan L. Alinea, Takahiro Kubota

We perform adiabatic regularization of power spectrum in nonminimally coupled general single-field inflation with varying speed of sound. The subtraction is performed within the fr…

The double-soft limit in cosmological correlation functions and graviton exchange effects

Allan L. Alinea, Takahiro Kubota, Nobuhiko Misumi

The graviton exchange effect on cosmological correlation functions is examined by employing the double-soft limit technique. A new relation among correlation functions that contain…

Adiabatic regularisation of power spectra in nonminimally coupled chaotic inflation

Allan L. Alinea

We investigate the effect of adiabatic regularization on both the tensor- and scalar-perturbation power spectra in \textit{nonminimally} coupled chaotic inflation. Similar to that…

Gender gap and polarisation of physics on global courses

Allan L. Alinea, Wade Naylor

We extend on previous research on the Force Concept Inventory (FCI) given to first year classical mechanics students (N=66 students, over four years) pre and post score, for studen…

Logarithmic divergences in the -inflationary power spectra computed through the uniform approximation

Allan L. Alinea, Takahiro Kubota, Wade Naylor

We investigate a calculation method for solving the Mukhanov-Sasaki equation in slow-roll -inflation based on the uniform approximation (UA) in conjunction with an expansion sch…

Adiabatic regularisation of power spectra in -inflation

Allan L. Alinea, Takahiro Kubota, Yukari Nakanishi +1

We look at the question posed by Parker et al. about the effect of UV regularisation on the power spectrum for inflation. Focusing on the slow-roll -inflation, we show that up t…

Polarization of physics on global courses

Allan L. Alinea, Wade Naylor

Since October 2010, the Chemistry-Biology Combined Major Program (CBCMP), an international course taught in English at Osaka University, has been teaching small classes (no more th…
