Axisymmetric force-free magnetospheres and theoretical models beyond general relativity: Magnetic moment of axion stars
(Pleiades Publishing, 2019-11)
Abstract: The magnetosphere structure of a magnetar is considered in the context of a theory of gravity with dynamical torsion field beyond the standard General Relativity (GR) with the purpose of determining in a theoretical ...
Dark matter stars from beyond General Relativity models: Magnetosphere dynamics and torsion fields
(Elsevier, 2020-06)
The magnetosphere structure of compact objects is considered in the context of a theory of gravity with dynamical torsion field beyond standard General Relativity (GR) introduced previously in Cirilo-Lombardo and Minotti ...
Beyond general relativity models, magnetosphere structure and dark matter stars
(World Scientific, 2019-03-19)
The magnetosphere structure of compact objects is considered in the context of a theory of gravity with dynamical torsion field beyond standard General Relativity (GR). To this end, a new spherically symmetric solution is ...
The quest for an intermediate-scale accidental axion and further ALPs
(Springer, 2014-06-06)
The recent detection of the cosmic microwave background polarimeter experiment BICEP2 of tensor fluctuations in the B-mode power spectrum basically excludes all plausible axion models where its decay constant is above ...
Subjective modeling decisions can significantly impact the simulation of flood and drought events
(Elsevier B.V., 2019)
© 2018 The Author(s)It is generally acknowledged in the environmental sciences that the choice of a computational model impacts the research results. In this study of a flood and drought event in the Swiss Thur basin, we ...
Symmetries as a guide to regularization ambiguities: Standard and Beyond Standard Model examples
(Universidade Federal de Minas GeraisUFMG, 2014-09-15)
This thesis is about regularization of ultraviolet divergences appearing in the perturbative expansion of quantum field theories (QFTs). We present a general view of the ambiguities that may arise in the regularization ...
What is a singular black hole beyond General Relativity?
(American Physical Society, 2017-03)
Exploring the characterization of singular black hole spacetimes, we study the relation between energy density, curvature invariants, and geodesic completeness using a quadratic f (R) gravity theory coupled to an anisotropic ...
Meson decays and physics beyond standard model
(2010)
In this thesis we discuss possible effects of new physics beyond the Standard Model
(SM) associated with high energy scales. We make special emphasis on their manifestations
in low energy processes such as meson decays. ...
