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 […]

Scientists find clues to suggest new type of neutrino Hints of the existence of an elusive sterile neutrino have been detected in the Daya Bay nuclear reactor facility near Hong Kong. This would be the first discovery of a particle which cannot be accommodated in the framework of the so-called standard model. Science News Quantum […]

Usually, the concept of exciton is linked to that of nonmetallic crystal: an electron-hole pair in a crystal that is bound in a manner analogous to the electron and proton of a hydrogen atom. It behaves like an atomic excitation (hence the name) that passes from atom to another and may be long-lived. Exciton behaviour […]

Some decades ago, the American social scientist Donald T. Campbell imagined interdisciplinary research as a fish-scale structure according to which scholars should make an effort to create links between disciplines, spanning areas ignored by others, in an overlapping pattern aiming to cover the entire web of knowledge. He suggested that scholars should overcome the “ […]

Science news with bad titles usually attract a lot of attention. A recent example is “The sound of an atom has been captured” ]. Laypeople must know that atoms do not emit sound. Quantum acoustics study the propagation and the interaction of phonons, the analogues in sound to photons in light. An atom cannot emit […]

Robert Hooke discovered the cell in 1665. Plenty of years passed until the human being, in less than three decades, went from elucidate DNA structure (1953) to control artificially the genetic expression of a living cell. Thorough knowledge of the life´s language (genetic code) and information flows (DNA–>RNA–>Protein) was paramount to achieve such a goal […]

It is not risky at all to assert that fundamental physics has not been in good shape in the last forty years or so, not because of lack of work, talent, conjectures and resources, but because few really big advances (as big as, say, the discovery of thermodynamics, of relativity, of quantum field theory, or […]

Organic chemistry uses lots and lots of names. Not only purely chemical names, but people’s names. This is so because the field is so broad that you need to name not only substances, that usually have two names, the official – from IUPAC rules – and the nickname, usually much shorter and easier to remember […]

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 usually mentioned behind the experimental and theoretical studies of graphene are the exceptional electronic properties, in particular the high electron mobilities, the long spin coherence lengths and the possibility […]

Ionization is a fundamental process in chemistry and physics, lying at the heart of many fascinating phenomena. Ionization is the process of producing ions. Certain molecules ionize in solution, for example. But ions may also be formed when an atom or molecule loses one or more electrons as a result of energy gained in a […]
