Researchers generate tunable twin particles of light

Identical twins might seem 'indistinguishable,' but in the quantum world the word takes on a new level of meaning. While identical twins share many traits, the universe treats two indistinguishable quantum particles as intrinsically interchangeable. This opens the door for indistinguishable particles to interact in unique ways—such as in quantum interference—that are needed for quantum computers.

Researchers develop magnetic thin film for spin-thermoelectric energy conversion

A team of researchers, affiliated with UNIST has recently introduced a new class of magnetic materials for spin caloritronics. Published in the February 2021 issue of Nature Communications, the demonstrated STE applications of a new class of magnets will pave the way for versatile recycling of ubiquitous waste heat. This breakthrough has been led by Professor Jung-Woo Yoo and his research team in the Department of Materials Science and Engineering at UNIST.

Researchers use optical data to reveal the basic structure of spacetime in rotating frames

One of the most basic structural aspects of relativistic spacetime is the description of how time and distances are altered by motion. The theory of special relativity describes a spacetime framework for linear constant motion in which time dilates and lengths contract in response to motion. This framework is described by the Lorentz transformation, which encompasses mathematical formulas that describe how time and distance are altered between moving reference frames. The Lorentz transformation also describes how a stationary observer views time in the moving frame to be offset with distance. The offsetting of time with distance between reference frames generates differential simultaneity, in which events that are simultaneous for one observer will not be simultaneous for a second observer moving relative to the first observer.

The brain game: What causes engagement and addiction to video games?

History tells us that games are an inseparable facet of humanity, and mainly for good reasons. Advocates of video games laud their pros: they help develop problem-solving skills, socialize, relieve stress, and exercise the mind and body—all at the same time! However, games also have a dark side: the potential for addiction. The explosive growth of the video game industry has spawned all sorts of games targeting different groups of people. This includes digital adaptations of popular board games like chess, but also extends to gambling-type games like online casinos and betting on horse races. While virtually all engaging forms of entertainment lend themselves to addictive behavior under specific circumstances, some video games are more commonly associated with addiction than others. But what exactly makes these games so potentially addictive?

Why perovskite solar cells tend to segregate under the influence of light

Solar cells made of perovskite are cheap, easy to produce, and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite cells have a love-hate-relationship with the Sun. The light that they need to generate electricity also happens to impair the quality of the cells, thus severely limiting their efficiency and stability over time. Researchers at Eindhoven University of Technology have now developed a theory that explains why compound perovskite cells are unstable in sunlight. The study was published in Nature Communications.

Novel circuitry solves multiple computationally intensive problems with minimum energy

From the branching pattern of leaf veins to the variety of interconnected pathways that spread the coronavirus, nature thrives on networks—grids that link the different components of complex systems.

A new method simulates the universe 1000 times faster

Cosmologists love universe simulations. Even models covering hundreds of millions of light years can be useful for understanding fundamental aspects of cosmology and the early universe. There's just one problem—they're extremely computationally intensive. A 500-million-light-year swath of the universe could take more than three weeks to simulate. Now, scientists led by Yin Li at the Flatiron Institute have developed a way to run these cosmically huge models 1000 times faster. That 500-million-year light-year swath could then be simulated in 36 minutes.
