Realisations of type III stress-energy tensors of the Hawking-Ellis classification in scalar-tensor gravity
Narayan Banerjee, Valerio Faraoni, Robert Vanderwee +1
The ``ugly duckling'' of the Segré-Plebański-Hawking-Ellis classification of stress-energy tensors is believed to be either impossible or extremely difficult to realise in Einstein…
Tolman-Ehrenfest's criterion of thermal equilibrium extended to conformally static spacetimes
Valerio Faraoni, Robert Vanderwee
With insight from examples and physical arguments, the Tolman-Ehrenfest criterion of thermal equilibrium for test fluids in static spacetimes is extended to local thermal equilibri…
Scalar field as a perfect fluid: thermodynamics of minimally coupled scalars and Einstein frame scalar-tensor gravity
Valerio Faraoni, Serena Giardino, Andrea Giusti +1
We revisit the analogy between a minimally coupled scalar field in general relativity and a perfect fluid, correcting previous identifications of effective temperature and chemical…
Friedmann-Lemaître-Robertson-Walker cosmology through the lens of gravitoelectromagnetism
Valerio Faraoni, Geneviève Vachon, Robert Vanderwee +1
Friedmann-Lemaître-Robertson-Walker cosmology is examined from the point of view of gravitoelectromagnetism, in the approximation of spacetime regions small in comparison with the…
Revisiting geodesic observers in cosmology
Geneviève Vachon, Robert Vanderwee, Valerio Faraoni
Geodesic observers in cosmology are revisited. The coordinates based on freely falling observers introduced by Gautreau in de Sitter and Einstein-de Sitter spaces (and, previously,…
