Quantum simulation of fermionic models in superconducting circuits
(2017-09-20)
Investigamos varios métodos de simulación cuántica de modelos fermiónicos, y damos cuenta de una implementación de una de nuestras propuestas en un soporte de circuitos superconductores. Partiendo de la usual codificación ...
Non-Abelian anomalies and hadronic fluids
(IOP, 2019)
By using differential geometry methods, we study the role of non-Abelian anomalies in relativistic fluids. We obtain closed expressions for the covariant currents derived from the Chern-Simons effective action. Our results ...
Thermodynamics of Resonant Scalars in AdS/CFT and implications for QCD
(E. D. P Sciences, 2016)
We explore the thermodynamics of a simple 5D Einstein-dilaton gravity model with a massive scalar field, with asymptotically AdS behavior in the UV. The holographic renormalization is addressed in details, and analytical ...
Solitons and black hole in shift symmetric scalar-tensor gravity with cosmological constant
(Springer, 2018-06-14)
We demonstrate the existence of static, spherically symmetric globally regular, i.e. solitonic solutions of a shift-symmetric scalar-tensor gravity model with negative cosmological constant. The norm of the Noether current ...
Fitting BICEP2 with defects, primordial gravitational waves and dust
(IOP Publishing, 2015)
In this work we discuss the possibility of cosmic defects being responsible for the B-mode signal measured by the BICEP2 collaboration. We also allow for the presence of other cosmological sources of B-modes such as ...
Spacelike submanifolds, their umbilical properties and applications to gravitational physics.
(2017-10-13)
Hasta aproximadamente el siglo dieciocho los científicos eran expertos tanto en los aspectosmatemáticos como en los aspectos físicos de su investigación y de sus descubrimientos.Cabe sostener que muy probablemente estos ...
Double layers in gravity theories
(IOP Publishing, 2015)
Gravitational double layers, unlike their classical electromagnetic counterparts, are thought to be forbidden in gravity theories. It has been recently shown, however, that they are feasible in, for instance, gravity ...
A phenomenological exploration within Theoretical Cosmology: from the Early to the Late Universe.
(2018-10-11)
En esta tesis se han explorado posibles extensiones del Modelo Estándar de la Cosmología. Hemos obtenido las predicciones teóricas de los modelos considerados y sus principales características. Los resultados presentados ...
Matching of spacetimes theory applied to rotating stars and quadratic gravity
(2016-04-29)
Este resumen contiene un repaso breve de las actividades de investigación que se han
llevado a cabo durante el desarrollo de la presente tesis doctoral, realizada con la ayuda
predoctoral del Gobierno Vasco (BFI-2011-250) ...
Hartle's model within the general theory of perturbatiye matchings: the change in mass
(IOP Publishing, 2015)
Hartle's model provides the most widely used analytic framework to describe isolated compact bodies rotating slowly in equilibrium up to second order in perturbations in the context of General Relativity. Apart from some ...
