An assessment of Evans' unified field theory I [PDF]

, 2007
Evans developed a classical unified field theory of gravitation and electromagnetism on the background of a spacetime obeying a Riemann-Cartan geometry. This geometry can be characterized by an orthonormal coframe theta and a (metric compatible) Lorentz ...

An assessment of Evans' unified field theory II [PDF]

, 2007
Evans developed a classical unified field theory of gravitation and electromagnetism on the background of a spacetime obeying a Riemann-Cartan geometry. In an accompanying paper I, we analyzed this theory and summarized it in nine equations.

Unification of elementary forces in gauge SL(2N,C) theories

Physics Letters B, 2022
We argue that the gauge SL(2N,C) theories may point to a possible way where the known elementary forces, including gravity, could be consistently unified. Remarkably, while all related gauge fields are presented in the same adjoint multiplet of the SL(2N,

No scale SUGRA SO(10) derived Starobinsky model of inflation

Physics Letters B, 2015
We show that a supersymmetric renormalizable theory based on gauge group SO(10) and Higgs system 10⊕210⊕126⊕126‾ with no scale supergravity can lead to a Starobinsky kind of potential for inflation. Successful inflation is possible in the cases where the

Unified non-metric (1, 0) tensor-Einstein supergravity theories and (4, 0) supergravity in six dimensions

Journal of High Energy Physics, 2021
The ultrashort unitary (4, 0) supermultiplet of 6d superconformal algebra OSp(8∗|8) reduces to the CPT-self conjugate supermultiplet of 4d superconformal algebra SU(2, 2|8) that represents the fields of maximal N = 8 supergravity. The graviton in the (4,

Mechanical Analysis of Frozen Wall with Trapezoidal Temperature Field Distribution Based on Unified Strength Theory

Applied Sciences, 2022
In order to study the elastic–plastic stress field distribution of a double-row-pipe frozen wall, the temperature field of the double-row-pipe frozen wall is equivalent to a trapezoidal distribution, and the frozen wall is regarded as an elastic–plastic ...

Unified theory in the worldline approach

Physics Letters B, 2015
We explore unified field theories based on the gauge groups SU(5) and SO(10) using the worldline approach for chiral fermions with a Wilson loop coupling to a background gauge field.

The Partnership Paradigm Is A Unified Field Theory For Human Betterment: How It Works in the Minnesota Climate Crisis Movement

Interdisciplinary Journal of Partnership Studies, 2016
“Intersectionality” is a byword of activists today. While we continue to ply our special causes and organize our various turfs, we are no longer content or even able to isolate ourselves within them as if they were solitary silos.

Is There a Correspondence Between “Orientalism” and The Orient? – Said, Dyson and Sen

IAFOR Journal of Cultural Studies, 2022
The study of cultural encounters has thrown up many important methodological and theoretical issues. Besides, these studies often rely on certain underlying socio-political and economic theories too.

Unified molecular field theory of nematic, smectic-A, and smectic-C phases [PDF]

, 2013
A unified mean-field molecular theory of nematic (NU), smectic A (SmA), and smectic C (SmC) liquid crystal phases, composed of uniaxial nonpolar molecules, is developed taking into account the variation of all orientational and translational order ...
