An international research team led by scientists at the University of California, Riverside, has observed light emission from a new type of transition between electronic valleys, known as intervalley transmissions. The research provides a new way to read out valley information, potentially leading to new types of devices.
Scientists have pioneered a new technique to expose hidden biochemical pathways involving single molecules at the nanoscale.
In 2005, Science asked if it was possible to develop a magnetic semiconductor that could work at room temperature. Now, just fifteen years later, researchers at Stevens Institute of Technology have developed those materials in two-dimensional form, solving one of science's most intractable problems.
An innovative radiation treatment that could one day be a valuable addition to conventional radiation therapy for inoperable brain and spinal tumors is a step closer, thanks to new research led by University of Saskatchewan (USask) researchers at the Canadian Light Source (CLS).
The measurement of a strontium ion lasts barely a millionth of a second but the researchers have managed to make a 'film' of the process by reconstructing the quantum state of the system at different moments. The results confirm one of the most subtle predictions in quantum physics.
A new machine learning tool can calculate the energy required to make -- or break -- simple molecules with higher accuracy than conventional methods. Extensions to more complicated molecules may help reveal the inner workings of the chemical reactions that nourish the global ecosystem.
Graphene is a diamagnetic material, this is, unable of becoming magnetic. However, a triangular piece of graphene is predicted to be magnetic. This apparent contradiction is a consequence of 'magic' shapes in the structure of graphene flakes, which force electrons to 'spin' easier in one direction. Triangulene is a triangular graphene flake, which possesses a net magnetic moment: it is a graphene nanometer-size magnet. This magnetic state opens fascinating perspectives on the use of these pure-carbon magnets in technology.
Researchers at the National Institute of Standards and Technology (NIST) and their colleagues at the University of Maryland have developed a step-by-step recipe to produce single-atom transistors.
A recent study at the Okinawa Institute of Science and Technology Graduate University has described new states that can be found in super-cold atom experiments, which could have applications for quantum technology.
In physics, thermalization, or the trend of sub-systems within a whole to gain a common temperature, is typically the norm. There are situations, however, where thermalization is slowed down or virtually suppressed; examples are when considering the dynamics of electron and nuclear spins in solids. Understanding why this happens and how it can be controlled is presently at the center of a broad effort, particularly for applications in the emerging field of quantum information technologies.
