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 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…
