On measuring the Quantum Universe
David Vasak, Johannes Kirsch, Juergen Struckmeier
We present a theoretical analysis of the WDW approach to quantum cosmology extended to gravity theories with torsion. The dynamics of the FLRW universe is formulated as a classical…
Massive propagating modes of torsion
Vladimir Denk, David Vasak, Johannes Kirsch
The dynamics of the torsion field is analyzed in the framework of the Covariant Canonical Gauge Theory of Gravity (CCGG), a De~Donder-Weyl Hamiltonian formulation of gauge gravity.…
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…
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…
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…
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…
Dark energy and inflation invoked in CCGG by locally contorted space-time
David Vasak, Johannes Kirsch, Juergen Struckmeier
The cosmological implications of the Covariant Canonical Gauge Theory of Gravity (CCGG) are investigated. We deduce that, in a metric compatible geometry, the requirement of covari…
Covariant Canonical Gauge Gravitation and Cosmology
David Vasak, Johannes Kirsch, Dirk Kehm +1
The covariant canonical transformation theory applied to the relativistic Hamiltonian theory of classical matter fields in dynamical space-time yields a novel (first order) gauge f…
Generic Theory of Geometrodynamics from Noether's theorem for the Diff(M) symmetry group
Jürgen Struckmeier, David Vasak, Johannes Kirsch
We work out the most general theory for the interaction of spacetime geometry and matter fields -- commonly referred to as geometrodynamics -- for spin- and spin- particles.…

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…
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…
Canonical Transformation Path to Gauge Theories of Gravity
J. Struckmeier, J. Muench, D. Vasak +3
In this paper, the generic part of the gauge theory of gravity is derived, based on the action principle and on the general principle of relativity. We apply the canonical transfor…
Probing QED Vacuum with Heavy Ions
Johann Rafelski, Johannes Kirsch, Berndt Müller +2
We recall how nearly half a century ago the proposal was made to explore the structure of the quantum vacuum using slow heavy-ion collisions. Pursuing this topic we review the foun…
Gauge Theory by canonical Transformations
Adrian Koenigstein, Johannes Kirsch, Horst Stoecker +3
Electromagnetism, the strong and the weak interaction are commonly formulated as gauge theories in a Lagrangian description. In this paper we present an alternative formal derivati…
