Is the physical vacuum a preferred frame?

Se p 20 07 Is the physical vacuum a preferred frame ?

It is generally assumed that the physical vacuum of particle physics should be characterized by an energy momentum tensor in such a way to preserve exact Lorentz invariance. On the other hand, if the ground state were characterized by its energy-momentum vector , with zero spatial momentum and a non-zero energy, the vacuum would represent a preferred frame. Since both theoretical approaches hav...

Quantization of the tachyonic field and the preferred frame

A consistent quantization scheme for imaginary-mass field is proposed. It is related to an appropriate choice of the synchronization procedure (definition of time), which guarantee an absolute causality in agreement with Lorentz covariance. In that formulation a possible existence of field excitations (tachyons) distinguish an inertial frame (tachyon privileged frame of reference) via spontaneo...

Postrelativity — A Paradigm For Quantization With Preferred Newtonian Frame

We define a new paradigm — postrelativity — based on the hypothesis of a preferred hidden Newtonian frame in relativistic theories. It leads to a modification of general relativity with ether interpretation, without topological problems, black hole and big bang singularities. Semiclassical theory predicts Hawking radiation with evaporation before horizon formation. In quantum gravity there is n...

The ‘Preferred Model’ for Australia’s Research Quality Frame- work

In a nutshell, the Preferred Model would lead to a methodology for research assessment that has many similarities to the UK Research Assessment Exercise, or RAE. The latter has been in operation since 1986; the sixth RAE will take place during 2008. The development of an RQF was signalled by the Prime Minister back in May 2004, in connection with the second tier of the gov-ernment's 'Backing Au...
