The direct search for dark matter has been a thriving experimental field since a couple of decades, and a new and promising experimental approach has been recently developed and tested: the use of an atomic clock inner mechanics. This whole […]

Faster. That is the word that describes de evolution of electronics. Any new development has to be faster than anything before, if it is going to cope with the huge amount of information that the device where it may be […]

Author: Álvaro Peralta Conde is a senior researcher at CLPU (Pulsed Lasers Centre). Although unfortunately it takes place in rare situations, the synergies between scientific and artistic disciplines offer a vast number of possible applications. The benefits are clear: on […]

The importance of water is paramount. Life, as we know it, would be unthinkable without it. Not only that, the geology of our planet, and those of other planets, can not be properly understood without a knowledge of how […]

The purpose of this note is to introduce the reader to the notion of Lipschitz structure and its potential applications to the spin geometry required to globally formulate string theory and supergravity on a differentiable manifold. . Spinors are a crucial […]

Luthiers still use Chladni figures in the design and construction of acoustic instruments such as violins, guitars, and cellos. The technique invented by the German physicist and musician Ernst Chladni (1756–1827) shows the modes of vibration under forcing. The […]

In previous posts, we have reviewed the different loopholes of Bell experiments. To make a long story short, entanglement experiments are based on measuring some magnitudes in two quantum systems, calculating a value based on the outcomes of these measurements, […]

Graphene is a two-dimensional allotrope of carbon made of hexagons. In February 2015, penta-graphene, only made of pentagons, was theoretically proposed as another two-dimensional allotrope of carbon . Apparently, it is dynamically, thermally, and mechanically stable, exhibiting a large band […]

In order to study new solid state magnetic properties appropiate new laboratory models are needed. In particular, there is a necessity for a substrate to investigate new forms of magnetic coupling with nanoscale ferromagnets and the exotic physics at the […]

The success of Bohr’s model of the atom in accounting for the spectrum of hydrogen left this question: Could experiments show directly that atoms do have only certain, separate energy states? In other words, are there really gaps between the […]
