The captured electrons typically absorb light in the visible spectrum, so that a transparent material becomes colored under the presence of such centers, for instance in diamond. "Color centers are often coming along with ...
Integrated photonics allow us to build compact, portable, low-power chip-scale optical systems used in commercial products, revolutionizing today's optical datacenters and communications. But integrating on-chip optical gain ...
The color in a diamond comes from a defect, or "vacancy," where there is a missing carbon atom in the crystal lattice. Vacancies have long been of interest to electronics researchers because they can be used as 'quantum nodes' ...
At first glance, heat and cold do not have much to do with quantum physics. A single atom is neither hot nor cold. Temperature can traditionally only be defined for objects that consist of many particles. But at TU Wien, ...
In the depths of space, there are celestial bodies where extreme conditions prevail: Rapidly rotating neutron stars generate super-strong magnetic fields. And black holes, with their enormous gravitational pull, can cause ...
Professor Konstantin Arutyunov of the HSE Tikhonov Moscow Institute of Electronics and Mathematics (MIEM HSE), together with Chinese researchers, has developed a graphene-based mechanical resonator, in which coherent emission ...
Almost a century ago, Albert Einstein received the Nobel Prize for Physics for his explanation of the photoelectric effect. Published in 1905, Einstein's theory incorporated the idea that light is made up of particles called ...
In recent years, physical reservoir computing, one of the new information processing technologies, has attracted much attention. This is a physical implementation version of reservoir computing, which is a learning method ...
Scientists at Sandia National Laboratories have built the world's smallest and best acoustic amplifier. And they did it using a concept that was all but abandoned for almost 50 years.
To change the direction of motion of a massive object, such as a car, it has to be slowed down and brought to a complete standstill first. Even the tiniest charge carriers in the universe, the electrons, follow this rule. ...
