Lorentz Violation in Emergent Gravity and Its Cosmological Consequences
Raymond Isichei, Joao Magueijo
We show that General Relativity and other geometrical theories can be viewed as a degenerate Otto cycle with only heat-exchange legs in emergent gravity. Including work-producing l…

Thermodynamics in space-times without horizons
Raymond Isichei, João Magueijo
We consider the energetics and thermodynamics of spacetimes with no horizons, but endowed with a preferred timelike junction surface. They could arise as a limiting case of the gra…

Attracting without being attracted: Dark Matter as an aether wind
Raymond Isichei, Joao Magueijo
We explore the possibility that part of what we call dark matter may be the mark of a preferred frame, revealing a breakdown of diffeomorphism invariance. In the non-relativistic l…
