UT Arlington research uses nanotechnology to help cool electrons with no external sources

September 11, 2014 4:35 pm | by EurekAlert! | Comments

A team of researchers has discovered a way to cool electrons to −228 °C without external means and at room temperature, an advancement that could enable electronic devices to function with very little energy. The process involves passing electrons....

New study examines impact of violent media on the brain

September 11, 2014 4:12 pm | by EurekAlert! | Comments

With the longstanding debate over whether violent movies cause real world violence as a backstop, a study published today in PLOS One found that each person's reaction to violent images depends on that individual's brain circuitry, and on how ...

Excitonic dark states shed light on TMDC atomic layers

September 11, 2014 4:07 pm | by EurekAlert! | Comments

A team of Berkeley Lab researchers believes it has uncovered the secret behind the unusual optoelectronic properties of single atomic layers of transition metal dichalcogenide (TMDC) materials, the two-dimensional semiconductors that hold ...

The quantum revolution is a step closer

September 11, 2014 4:04 pm | by EurekAlert! | Comments

Theories show how computing devices that operate according to quantum mechanics can solve problems that conventional (classical) computers, including super computers, can never solve. These theories have been experimentally tested for ...

The sound of an atom has been captured

September 11, 2014 4:00 pm | by EurekAlert! | Comments

Researchers at Chalmers University of Technology are first to show the use of sound to communicate with an artificial atom. They can thereby demonstrate phenomena from quantum physics with sound taking on the role of light. The results ...
