Gravity from generalized entropy
Hussain Gohar
Gravity from entropy (GfE) identifies its Lagrangian with the geometric quantum relative entropy (GQRE) between the spacetime metric and a metric induced by matter and curvature, t…
Modified Cosmology from Mass-to-Horizon Relation: Observational Bounds
Pranav Prasanthan, Hussain Gohar, Vincenzo Salzano
We constrain the class of modified cosmologies derived in Paper I [1] from a generalized mass-to-horizon relation (MHR) that enforces thermodynamic consistency between the Cai-Kim…
Modified Cosmology from Mass-to-Horizon Relation: Background Evolution
Pranav Prasanthan, Hussain Gohar, Vincenzo Salzano
