Mario Herrero-Valea
Graduated in Physics by the University of Oviedo (Spain) and currently a PhD student at the Department of Theoretical Physics of the Autonomous University of Madrid (Spain) and a member of the Institute of Theoretical Physics of the Spanish Research Council (IFT, UAM-CSIC). He works in the area of Quantum Field Theories in curved space-times and General Relativity, currently studying the gravitational effect of the Higgs field in the context of the Dark Energy problem.

Of all the advances made in theoretical physics in the last twenty years, I still have no doubt that the most impressive one is the so called Maldacena’s conjecture, the guess that the physics involved in some models of […]

In the last days there has been an important breakthrough in physics and particularly in cosmology due to the publication of the results of the BICEP2 collaboration on the measure of certain polarization of the Cosmic Microwave Background (CMB) […]

Last month, a lot of newspapers and websites have been promoting this article on Nature referring to a recent preprint uploaded by Stephen W. Hawking to the internet repository ArXiv. In this work, summarizing what he talked about in […]

A lot of ink has been wasted in the last decades discussing whether string theory is a good description of nature or merely a mathematica construct with no connection at all with reality. However, the answer to this question actually […]

Disclaimer: What I will relate in this post is the result of my research during the last year and specially the results of my last paper, uploaded as a preprint to ArXiv.org with reference arXiv:1307.2060 . Apart from the self-promotion, […]

One of hottest topics in theoretical physics today is, of course, quantum gravity. The fact that, almost a hundred years after the born of the quantum theory, we still not have a functional theory that describes gravity at a microscopic […]

During the last year, a longtime forgotten controversy was reactivated by a very interesting paper written by J. Polchinski and his collaborators, in which they questioned whether the so called black hole complementarity principle is a good solution to […]

Quantum field theory has been the paradigm of modern physics since it was formulated in the first half of the last century. It is based on the idea that everything in physics corresponds to the interaction of some fundamental fields […]

We are almost sure: we have discovered the Higgs boson. Or at least, that is the most reasonable comment to do after the usual Winter Report given by the scientists that work on the two main experiments placed at the […]

Back in the decade of 1950, and inspired by the beauty of the formulation of Quantum Electrodynamics, carried out by Feynman among others in the first half of the twentieth century; scientists thought that all physics had to be invariant […]
