Well-defined equations of motion without constraint of external sources
Kevin S. Croker, Joel L. Weiner, Duncan Farrah
We present a new approach to constrained classical fields that enables the action formalism to dictate how external sources must enter the resulting equations of motion. If symmetr…
Cosmologically coupled compact objects: a single parameter model for LIGO--Virgo mass and redshift distributions
Kevin S. Croker, Michael J. Zevin, Duncan Farrah +2
We demonstrate a single-parameter route for reproducing higher mass objects as observed in the LIGO--Virgo mass distribution, using only the isolated binary stellar evolution chann…
Implications of Symmetry and Pressure in Friedmann Cosmology. I. Formalism
Kevin S. Croker, Joel L. Weiner
We show that derivation of Friedmann's equations from the Einstein-Hilbert action, paying attention to the requirements of isotropy and homogeneity during the variation, leads to a…
A Smolin-like branching multiverse from multiscalar-tensor theory
K. A. S. Croker
We implement a Smolin-like branching multiverse through a directed, acyclic graph of metrics. Our gravitational and matter actions are indistinguishable from decoupled stat…
