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. […]
In nature, light harvesting organisms make extensive use of energy and electron transfer between adjacent molecules. Thus, in the photosynthetic cell of an algae, bacterium, or plant, there are light-sensitive molecules called chromophores, which contain a π-conjugated system (a system […]
With “many-body problem” we usually make reference to one that is very difficult to obtain exact solutions for, because the system involves interactions between more than two bodies. This kind of problem appears both in classical and quantum systems.
Imagine you want to study the biology of an animal that no one has been able to capture. First, you devise a way of trapping it, then a method of calming it down so that you can manipulate it. This […]
The field of electronic transport through nanometer-scale systems, such as molecular junctions or atomic wires, has been an extremely active area during the last decades. The effect that the development of a post-silicon era might have on our daily lives, […]
The German mineralogist Gustav Rose (1798 – 1873) made important contributions in the fields of petrology and crystallography. He was the first to use a reflective goniometer in Germany and developed a particular interest in the relationship between the crystalline […]
Anyone who has studied, even superficially, some thermodynamics has encountered the word adiabatic very early. This is because adiabatic processes are extremely useful to understand the basics of the field. An adiabatic process is any process that occurs without heat […]
Japan is known to be one of the world technological leaders. Having to import many of the raw materials and fuels its industry needs, it has been basic research and the development of technologies based on it what have transformed […]
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 […]
As the search for renewable energy sources has intensified, the discovery of efficient and cheap technologies for exploiting the energy from the sunlight has emerged as a key challenge.
Higher efficiency plays an increasingly important role in making competitive […]
