Non-Gaussian features of chaotic Hamiltonian transport
Roberto Venegeroles, Alberto Saa
Some non-Gaussian aspects of chaotic transport are investigated for a general class of two-dimensional area-preserving maps. Kurtosis, in particular, is calculated from the diffusi…
The number of dimensional fundamental constants
George E. A. Matsas, Vicente Pleitez, Alberto Saa +1
We revisit, qualify, and objectively resolve the seemingly controversial question about what is the number of dimensional fundamental constants in Nature. For this purpose, we only…
Lifetime and decay of unstable particles in strong gravitational fields
Douglas Fregolente, Alberto Saa
We consider here the decay of unstable particles in geodesic circular motion around compact objects. For the neutron, in particular, strong and weak decay are calculated by means o…
Quasinormal mode characterization of evaporating mini black holes
Elcio Abdalla, Cecilia B. M. H. Chirenti, Alberto Saa
According to recent theoretical developments, it might be possible to produce mini black holes in the high energy experiments in the LHC at CERN. We propose here a model based on t…
Homogeneous cosmologies and the Maupertuis-Jacobi principle
Luciana A. Elias, Alberto Saa
A recent work showing that homogeneous and isotropic cosmologies involving scalar fields are equivalent to the geodesics of certain effective manifolds is generalized to the non-mi…
Non-Minimally Coupled Cosmology as Geodesic Motion
Luciana A. Elias, Alberto Saa
Recent works showing that homogeneous and isotropic cosmologies involving scalar fields correspond to geodesics of certain augmented spaces are generalized to the non-minimal coupl…
