Two-point functions with an invariant Planck scale and thermal effects
Ivan Agullo, Jose Navarro-Salas, Gonzalo J. Olmo +1
Nonlinear deformations of relativistic symmetries at the Planck scale are usually addressed in terms of modified dispersion relations. We explore here an alternative route by direc…
Acceleration radiation and the Planck scale
I. Agullo, J. Navarro-Salas, G. J. Olmo +1
A uniformly accelerating observer perceives the Minkowski vacuum state as a thermal bath of radiation. We point out that this field-theory effect can be derived, for any dimension…
Hydrogen atom in Palatini theories of gravity
Gonzalo J. Olmo
We study the effects that the gravitational interaction of theories of gravity in Palatini formalism has on the stationary states of the Hydrogen atom. We show that the role…
Limit to General Relativity in f(R) theories of gravity
Gonzalo J. Olmo
We discuss two aspects of f(R) theories of gravity in metric formalism. We first study the reasons to introduce a scalar-tensor representation for these theories and the behavior o…
Violation of the Equivalence Principle in Modified Theories of Gravity
Gonzalo J. Olmo
We study modified theories of gravity of the f(R) type in Palatini formalism. For a generic f(R) lagrangian, we show that the metric can be solved as the product of a scalar functi…
Nonlinear Gravity Theories in the Metric and Palatini Formalisms
Gonzalo J. Olmo, William Komp
We study nonlinear gravity theories in both the metric and the Palatini (metric-affine) formalisms. The nonlinear character of the gravity lagrangian in the metric formalism causes…
