A Strong Cosmologically Coupled Mass Growth Solution in Linearized General Relativity
Kevin S. Croker, Joshua Cohon, Viktor T. Toth +13
DESI Data Release 2 has heightened interest in cosmologically coupled black holes (CCBHs) as an explanation for accelerating late-time expansion, but known models for CCBHs grow to…
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…
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…
Generalizing Birkhoff
Joel L. Weiner
We generalize Birkhoff's Theorem in the following fashion. We find necessary and sufficient conditions for any spherically symmetric space-time to be static in terms of the eigenva…
Topology, Geometry, and Stability: Protein Folding and Evolution
Walter Simmons, Joel L. Weiner
The protein folding problem must ultimately be solved on all length scales from the atomic up through a hierarchy of complicated structures. By analyzing the stability of the foldi…
The Principle of Stationary Action in Biophysics: Stability in Protein Folding
Walter Simmons, Joel L. Weiner
Processes that proceed reliably from a variety of initial conditions to a unique final form, regardless of moderately changing conditions, are of obvious importance in biophysics.…
