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 merely on the action principle and on the general principle of relativity. We apply the canonical t…
Induced Couplings and Causal Bounds from Nondegenerate Dirac Lagrangians
Marcelo Netz-Marzola, David Vasak, Vladimir Denk +2
The standard Dirac Lagrangian is linear in the field derivatives and therefore has a vanishing Hessian. We identify the minimal null deformations of this Lagrangian that make the c…
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 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…
Setting free the cosmic time in Quantum Universe
David Vasak
The standard Wheeler-DeWitt approach to Quantum Cosmology leads to the problematic freeze of time. The reason is the enforcement of time re-parametrization invariance via the lapse…
