Local Geometric Bounds on Generalized Entropy Evolution along Null Horizons
Erik Bertram
We develop a local and covariant framework for constraining the evolution of generalized entropy along null horizons, combining classical geometric methods with constraints from qu…

From Triadic Interactions to Kolmogorov Scaling: A Deterministic, Scale-Resolved Formulation of Energy Flux
Erik Bertram
We develop a deterministic, scale-resolved formulation of energy transfer in the three-dimensional incompressible Navier-Stokes equations based on an explicit triadic decomposition…

A Momentum-Regulated Model For Star Formation Efficiency in Giant Molecular Clouds
Erik Bertram
We present a minimal analytic framework to investigate the star formation efficiency per free-fall time, , in giant molecular clouds (GMCs), focusing on the origin of t…
