Sign-Locked Gravitational Baryogenesis from Bulk Viscosity and Cosmological Particle Creation
Yakov Mandel
We study a concrete realization of gravitational baryogenesis in which a small bulk-viscous deformation of an otherwise radiation-dominated early universe generates a sign-definite…

Gravitational Baryogenesis from Entropy Production and Parity Violation: A Unified Framework
Yakov Mandel
We present a unified framework for gravitational baryogenesis combining two mechanisms: (i) an entropy-clock source that generates a sign-definite baryon chemical potential mu_B pr…

Baryogenesis from the Thermodynamic Arrow of Time: a Transfer-Function Bound and an Entropy-Clock Mechanism
Yakov Mandel
We formulate a transfer test for baryogenesis driven by time-dependent derivative sources. A zero-mean oscillatory chemical potential convolved with a smooth finite-time kernel is…
