Galactic dark matter halos: From anisotropic fluids in general relativity to Horava-Lifshitz gravity
Paolo M Bassani
We deform the GR Hamiltonian by adding an extra weight density to the potential. We show that potential deformations of this type leave the (reduced) Dirac algebra unchanged a…

Violations of energy conservation in Horava-Lifshitz gravity: a new ingredient in the dark matter puzzle
Paolo M Bassani, Joao Magueijo, Shinji Mukohyama
We investigate the interplay between Horava-Lifshitz (HL) gravity and more general theories where the local Hamiltonian constraint is lost, for example due to the time variability…

How to make a Universe
Paolo M Bassani, Joao Magueijo
We establish the general conditions under which evolution in the laws of physics and matter creation or destruction are closely intertwined. They make use of global time variables…
