Torsion nonminimally coupled to the electromagnetic field and birefringence
In conventional Maxwell–Lorentz electrodynamics, the propagation of light is influenced by the metric, not, however, by the possible presence of a torsion T . Still the light can feel torsion if the latter is coupled nonminimally to the electromagnetic field F by means of a supplementary Lagrangian of the type ∼ l2T 2 F 2 (l = coupling constant). Recently Preuss suggested a specific nonminimal ...
متن کاملFresh inflation with nonminimally coupled inflaton field
I study a fresh inflationary model with a scalar field nonminimally coupled to gravity. An example is examined. I find that, as larger is the value of p (a ∼ tp), smaller (but larger in its absolute value) is the necessary value of the coupling ξ to the inflaton field fluctuations can satisfy a scale invariant power spectrum.
متن کاملEnergy density of nonminimally coupled scalar field cosmologies.
Scalar elds coupled to gravity via R 2 in arbitrary Friedmann-RobertsonWalker backgrounds can be represented by an e ective at space eld theory. We derive an expression for the scalar energy density where the e ective scalar mass becomes an explicit function of and the scale factor. The scalar quartic self-coupling gets shifted and can vanish for a particular choice of . Gravitationally induced...

In this work we study the asymptotically flat, static, and spherically symmetric black-hole solutions of the theory described by the action
متن کاملNo hair for spherical black holes: Charged and nonminimally coupled scalar field with self-interaction.
Avraham E. Mayo and Jacob D. Bekenstein The Racah Institute of Physics, Hebrew University of Jerusalem, Givat Ram, Jerusalem 91904, Israel (March 1, 1996) We prove three theorems in general relativity which rule out scalar hair of static, spherically symmetric, possibly electrically charged black holes. We rst generalize Bekenstein's no{hair theorem for a multiplet of minimally coupled real sca...
