Tidal Forces in the Presence of Torsion and Nonmetricity
Armin van de Venn, Marcelo Netz-Marzola, David Vasak +1
This work investigates how torsion and nonmetricity modify tidal accelerations in metric-affine gravity. We derive a projected deviation equation that generalizes the standard geod…
On CCGG, the De Donder-Weyl Hamiltonian formulation of canonical gauge gravity
D. Vasak, J. Kirsch, A. van de Venn +2
This paper gives a brief overview of the manifestly covariant canonical gauge gravity (CCGG) that is rooted in the De Donder-Weyl Hamiltonian formulation of relativistic field theo…
Covariant Canonical Gauge Theory of Classical Gravitation for Scalar, Vector, and Spin-1/2 Particle Fields
David Vasak, Jürgen Struckmeier
The framework of the Covariant Canonical Gauge theory of Gravity (CCGG) is described in detail. CCGG emerges naturally in the Palatini formulation, where the vierbein and the spin…
Torsion driving cosmic expansion
Johannes Kirsch, David Vasak, Armin van de Venn +1
We study a cosmological model based on the canonical Hamiltonian transformation theory. Using a linear-quadratic approach for the free gravitational De Donder-Weyl Hamiltonian $H_\…
Torsional dark energy in quadratic gauge gravity
Armin van de Venn, David Vasak, Johannes Kirsch +1
The Covariant Canonical Gauge theory of Gravity (CCGG) is a gauge field formulation of gravity which a priori includes non-metricity and torsion. It extends the Lagrangian of Einst…
On the cosmological constant in the deformed Einstein-Cartan gauge gravity in De Donder-Weyl Hamiltonian formulation
D. Vasak, J. Kirsch, J. Struckmeier +1
A modification of the Einstein-Hilbert theory, the Covariant Canonical Gauge Gravity (CCGG), leads to a cosmological constant that represents the energy of the space-time continuum…
Identity for scalar-valued functions of tensors and its applications to energy-momentum tensors in classical field theories and gravity
J. Struckmeier, A. van de Venn, D. Vasak
We prove a theorem on scalar-valued functions of tensors, where ``scalar'' refers to absolute scalars as well as relative scalars of weight . The present work thereby generalize…
Low-Redshift Constraints on Covariant Canonical Gauge Theory of Gravity
David Benisty, David Vasak, Johannes Kirsch +1
Constraints on the Covariant Canonical Gauge Gravity (CCGG) theory from low-redshift cosmology are studied. The formulation extends Einstein's theory of General Relativity (GR) by…
Covariant canonical gauge theory of gravitation for fermions
Jürgen Struckmeier, David Vasak
We derive the interaction of fermions with a dynamical space-time based on the postulate that the description of physics should be independent of the reference frame, which means t…
Rigorous derivation of dark energy and inflation as geometry effects in Covariant Canonical Gauge Gravity
David Vasak, Johannes Kirsch, Jürgen Struckmeier
The cosmological implications of the Covariant Canonical Gauge Theory of Gravity (CCGG) are investigated. CCGG is a Palatini theory derived from first principles using the canonica…
Vanishing torsion coupling of the Maxwell field in canonical gauge theory of gravity
Johannes Münch, Jürgen Struckmeier, David Vasak
The Maxwell field can be viewed as a -gauge theory, therefore, generalizing it to form-invariance in dynamical spacetime backgrounds should take this symmetry into account. T…
Inflation from fermions with curvature-dependent mass
David Benisty, Eduardo I. Guendelman, Emmanuel N. Saridakis +3
A model of inflation realization driven by fermions with curvature-dependent mass is studied. Such a term is derived from the Covariant Canonical Gauge Theory of gravity (CCGG) inc…
Pauli-type coupling between spinors and curved spacetime
J. Struckmeier, D. Vasak, A. Redelbach +1
We investigate Pauli-type interactions generated by minimal coupling of a specified covariantly regular representative of the Dirac Lagrangian. A derivative-quadratic term proporti…
Quadratic curvature theories formulated as Covariant Canonical Gauge theories of Gravity
David Benisty, Eduardo I. Guendelman, David Vasak +2
The Covariant Canonical Gauge theory of Gravity is generalized by including at the Lagrangian level all possible quadratic curvature invariants. In this approach, the covariant Ham…
Energy transfer from space-time into matter and a bouncing inflation from Covariant Canonical Gauge theory of Gravity
David Benisty, David Vasak, Eduardo Guendelman +1
Cosmological solutions for covariant canonical gauge theories of gravity are presented. The underlying covariant canonical transformation framework invokes a dynamical space-time H…

Canonical transformation path to gauge theories of gravity II --- Spacetime coupling of spin-0 and spin-1 particle fields
J. Struckmeier, J. Muench, P. Liebrich +5
The generic form of spacetime dynamics as a classical gauge field theory has recently been derived, based on only the action principle and on the Principle of General Relativity. I…
General relativity as an extended canonical gauge theory
Jürgen Struckmeier
It is widely accepted that the fundamental geometrical law of nature should follow from an action principle. The particular subset of transformations of a system's dynamical variab…
