Friedmann equations from nonequilibrium thermodynamics of the Universe: A unified formulation for modified gravity

David Wenjie Tian, Ivan Booth

Inspired by the Wald-Kodama entropy $S = A / (4 G_{eff})$ where $A$ is the horizon area and $G_{eff}$ is the effective gravitational coupling strength in modified gravity…

Lessons from $f (R, R_{c}^{2}, R_{m}^{2}, L_{m})$ gravity: Smooth Gauss-Bonnet limit, energy-momentum conservation and nonminimal coupling

David Wenjie Tian, Ivan Booth

This paper studies a generic fourth-order theory of gravity with Lagrangian density $f (R, R_{c}^{2}, R_{m}^{2}, L_{m})$ . By considering explicit $R^{2}$ dependence and imposing the "co…
