So-called “valleytronics” is a new type of electronics that could lead to faster and more efficient computer logic systems and data storage chips in next-generation devices. Valley electrons are so named because they carry a valley “degree of freedom.” This is a new way to harness electrons for information processing that’s in addition to utilizing […]

We have considered in some previous articles the importance of the spin-orbit interaction. But it is interesting to go through some basic concepts we have seen elsewhere once again in order to grasp the surprising discovery we will be talking about below. The analogy for the spin usually goes this way: Imagine that the electron […]

Since the discovery that graphene, the two dimensional carbon allotrope, can be isolated and incorporated into electronic devices intense research efforts have been triggered. Driving forces behind the experimental and theoretical studies of graphene are, e.g., the exceptional electronic properties, in particular the high electron mobilities, the long spin coherence lengths and the possibility to […]

We know that incident light can provoke a strong optical response in metallic nanostructures due to the excitation of resonant plasmonic modes, i.e, the electrons in the metal become excited by the photons in the incident light and oscillate collectively. Plasmonic nanoparticles can significantly modify the optical properties of nearby organic molecules and thus present […]

The Pioneer plaques are a pair of gold–anodized aluminium plaques which were placed on board the 1972 Pioneer 10 and 1973 Pioneer 11 spacecraft, featuring a pictorial message, in case either Pioneer 10 or 11 is intercepted by extraterrestrial life. The plaques show the nude figures of a human male and female along with several […]

Antimicrobial resistance is a complex problem that contributes to health and economic losses worldwide. Resistance to antimicrobial therapies reduces the effectiveness of current drugs, leading to increased morbidity, mortality, and health care expenditure. Because globalization increases the vulnerability of any country to diseases occurring in other countries, resistance presents a major threat to global public […]

Graphene is one of the most promising materials for nanoelectronics owing to its unique Dirac cone-like dispersion of the electronic state and high mobility of the charge carriers. We all know that already, provided we are a little bit interested in condensed matter physics. But the point is that, in order to facilitate the implementation […]

How would you measure the dynamic viscosity of cytosol, the liquid inside the cells, without destroying the cell? It seems not an easy task. However, a team of researchers that includes Nuno de Sousa (DIPC & IFIMAC), has just provided a way of achieving this and other similar feats using upconverting particles. An optical trap […]

Worldwide research efforts on plasmons and metamaterials have been growing exponentially for the past ten years. Now, Antonio I. Fernández-Domínguez (IFIMAC), Francisco J. García-Vidal (IFIMAC & DIPC), and Luis Martín-Moreno (ICMA) discuss new directions for the future, such as the use of 2D materials and strong coupling phenomena, which are likely to shape the field […]

Imagine there exist a material in which an electron could be split into two quasiparticles. These two quasiparticles both would carry electric charge, move in opposite directions but could not move backwards. Furthermore these quasiparticles would be massless. And we can give them a fancy name, Weyl fermions. This seems to be at odds with […]
