The vacuum energy from a new perspective Academic Article uri icon

abstract

  • It is commonly believed that the vacuum energy problem points to the need for (1) a radically new formulation of gravitational physics and (2) a new principle which forces the vacuum stress-energy tensor (as measured by gravity) to be nearly zero. Here we point out that a new fundamental theory contains both features: (1) In this theory the vierbein is interpreted as the "superfluid velocity" associated with the order parameter for a GUT-scale Higgs condensate. (2) The vacuum stress-energy tensor is exactly zero in the vacuum state, because the action is extremalized with respect to variations in the order parameter. With inhomogeneously-distributed matter present, the vacuum stress-energy tensor is shifted away from zero.
