Creating custom light using 2D materials

Making artificial structures that emit light tailored to our specific needs is an even more attractive proposition. However, light emission in a semi-conductor only occurs when certain conditions are met. Researchers have discovered an entire class of two-dimensional materials that are the thickness of one or a few atoms. When combined together, these atomically thin crystals are capable of forming structures that emit customizable light in the desired color.

Physicists see nuclear wobbling in one isotope of gold

Nuclei can be round, like a soccer ball, or oblong, like a football. Others are slightly oblong but misshapen, like a potato. One of the only two ways to observe the third shape, rarely encountered, is when the nucleus wobbles like a lopsided top.

Physicists see nuclear wobbling in one isotope of gold

Researchers recently discovered that some nuclei wobble on their intermediate axes. 

Topological materials outperform through quantum periodic motion

Scientists have discovered that applying vibrational motion in a periodic manner may be the key to preventing dissipations of the desired electron states that would make advanced quantum computing and spintronics possible.

Novel Quantum effect found: Spin-rotation coupling

It is like jumping on and off a carousel: what happens to neutrons changing from a non-rotating frame of reference into a rotating frame of reference -- and back? 30 years ago, scientists predicted that this would lead to interesting interference effects, because neutron spin show a special kind of inertia. Now, this has been verified in an experiment.

New artificial neural network model bests MaxEnt in inverse problem example

Numerical simulations, generally based on equations that describe a given model and on initial data, are being applied in an ever-expanding range of scientific disciplines to approximate processes at given points in time and space. With so-called inverse problems, this critical data is missing—researchers must reconstruct approximations of the input data or of the model underlying observable data in order to generate the desired predictions.

Highly sensitive sensors show promise in enhancing human touch

People rely on a highly tuned sense of touch to manipulate objects, but injuries to the skin and the simple act of wearing gloves can impair this ability. Surgeons, for example, find that gloves decrease their ability to manipulate soft tissues. Astronauts are also hampered by heavy spacesuits and find it difficult to work with equipment while wearing heavy gloves.

MoEDAL hunts for dyons

A magnetic monopole is a theoretical particle with a magnetic charge. Give it an electric charge, and you get another theoretical beast, dubbed a dyon. Many "grand unified theories" of particle physics, which connect fundamental forces at high energies into a single force, predict the existence of dyons, but no experiments at particle accelerators have so far searched for these hybrid particles—until now.

New all-sky search reveals potential neutrino sources

For over a century, scientists have been observing very high-energy charged particles called cosmic rays arriving from outside Earth's atmosphere. The origins of these particles are very difficult to pinpoint because the particles themselves do not travel on a straight path to Earth. Even gamma rays, a type of high-energy photon that offers a little more insight, are absorbed when traversing long distances.
