From Nonmetricity Operators to the Physical Spectrum: A Branch-Complete Analysis of Local Four-Derivative Symmetric Teleparallel Gravity
Caglar Pala
We develop a branch-complete classical free-spectrum analysis of local parity-even symmetric teleparallel gravity containing all pure-gravity nonmetricity operators through four de…
Foldy--Wouthuysen Transformation of the Generalized Dirac Equation in Symmetric Teleparallel Gravity
Sabutay Ugur, Muzaffer Adak, Ali Bagci +1
We investigate the non-relativistic limit of the generalized Dirac equation in a weak, static, and spherically symmetric background of symmetric teleparallel gravity. The underlyin…
Symmetric teleparallel gravitational effects on solar neutrino oscillations
Aysel Cetinkaya, Muzaffer Adak, Ozcan Sert +1
Neutrino oscillations probe the quantum gravity interface in unique ways. While gravitational effects on neutrinos are well studied in general relativity and torsion based geometri…
Generalized Dirac Equation in Metric-Affine Spacetimes: Consistency, Effective Mass, and Spinor Curvature
Muzaffer Adak, Ali Bagci, Caglar Pala +1
We formulate a generalized Dirac equation in four-dimensional metric-affine spacetimes with curvature, torsion, and non-metricity. The spinor connection is expanded over the comple…
Weyl-Lorentz-U(1)-invariant symmetric teleparallel gravity in three dimensions
Muzaffer Adak, Nese Ozdemir, Caglar Pala
We consider a Weyl-Lorentz--invariant gravity model written in terms of a scalar field, electromagnetic field and nonmetricity without torsion and curvature, the so-called sy…
General teleparallel metrical geometries
Muzaffer Adak, Tekin Dereli, Tomi S. Koivisto +1
In the conventional formulation of general relativity, gravity is represented by the metric curvature of Riemannian geometry. There are also alternative formulations in flat affine…
Weyl covariance, second clock effect and proper time in theories of symmetric teleparallel gravity
Caglar Pala, Ozcan Sert, Muzaffer Adak
Just after Weyl's paper (Weyl in Gravitation und Elektrizität, Sitzungsber. Preuss. Akad., Berlin, 1918) Einstein claimed that a gravity model written in a spacetime geometry with…
A modified gravity model coupled to a Dirac field in 2D spacetimes with quadratic nonmetricity and curvature
Caglar Pala, Ertan Kok, Ozcan Sert +1
After summarizing basic concepts for the exterior algebra we firstly discuss the gauge structure of the bundle over base manifold for deciding the form of the gravitational sector…
A novel approach to autoparallels for the theories of symmetric teleparallel gravity
Muzaffer Adak, Caglar Pala
Although the autoparallel curves and the geodesics coincide in the Riemannian geometry in which only the curvature is nonzero among the nonmetricity, the torsion and the curvature,…
