Cosmic acceleration and a natural solution to the cosmological constant problem
Philip D. Mannheim
We trace the origin of the cosmological constant problem to the assumption that Newton's constant sets the scale for cosmology. And then we show that once this assumption is re…
The equivalence principle in classical mechanics and quantum mechanics
Philip D. Mannheim
We discuss our understanding of the equivalence principle in both classical mechanics and quantum mechanics. We show that not only does the equivalence principle hold for the traje…
Classical Underpinnings of Gravitationally Induced Quantum Interference
Philip D. Mannheim
We show that the gravitational modification of the phase of a neutron beam (the COW experiment) has a classical origin, being due to the time delay which classical particles experi…
Higgs Mechanism and the Structure of the Energy-Momentum Tensor in Einstein Gravity and Conformal Gravity
Philip D. Mannheim, Demosthenes Kazanas
In the standard treatment of the Einstein gravitational theory the energy-momentum tensor has always been taken to be composed of perfect fluid aggregates of kinematic Newtonian po…
