Physicists use light waves to accelerate supercurrents, enable ultrafast quantum computing

Scientists have discovered that terahertz light -- light at trillions of cycles per second -- can act as a control knob to accelerate supercurrents. That can help open up the quantum world of matter and energy at atomic and subatomic scales to practical applications such as ultrafast computing.

Transformer cells: Shaping cellular 'behaviour'

Scientists from Sechenov University, conjointly with their fellow Chinese and American researchers, have examined the latest advances in the use of skeletal muscle progenitor cells, specifying the core challenges inherent to the applicability of MPCs in cell therapy, and outlining the most promising breakthrough technologies. The outcomes of this research were reported in Applied Physics Reviews, the article having been roundly praised by the editorial board.

Life Among the Dwarfs

When I was an astronomy-obsessed kid, I learned that most of the stars in our galaxy and beyond are very similar to our Sun. No less an authority than Carl Sagan wrote that "the Sun is an ordinary, even a mediocre star." If that insight diminished the importance of our place in the universe, it also made it seem

Atomic 'patchwork' using heteroepitaxy for next generation semiconductor devices

Researchers have grown atomically thin crystalline layers of transition metal dichalcogenides (TMDCs) with varying composition over space, continuously feeding in different types of TMDC to a growth chamber to tailor changes in properties. Examples include 20nm strips surrounded by different TMDCs with atomically straight interfaces, and layered structures. They also directly probed the electronic properties of these heterostructures; potential applications include electronics with unparalleled power efficiency.

New material shows high potential for quantum computing

Scientists are getting closer to confirming the existence of an exotic quantum particle called Majorana fermion, crucial for fault-tolerant quantum computing -- the kind of quantum computing that addresses errors during its operation.

Utrafast magnetism: Electron-phonon interactions examined at BESSY II

How fast can a magnet switch its orientation and what are the microscopic mechanisms at play? These questions are of first importance for the development of data storage and computer chips. Now, an HZB team at BESSY II has for the first time been able to experimentally assess the principal microscopic process of ultra-fast magnetism. The methodology developed for this purpose can also be used to investigate interactions between spins and lattice oscillations in graphene, superconductors or other (quantum) materials.

Researchers teleport information within a diamond

Researchers have teleported quantum information securely within the confines of a diamond. The study has big implications for quantum information technology -- the future of how sensitive information is shared and stored.

New property of light discovered

A team of researchers affiliated with several institutions in Spain and the U.S. has announced that they have discovered a new property of light—self-torque. In their paper published in the journal Science, the group describes how they happened to spot the new property and possible uses for it.

Engineers report a new low-power lighting technology

Researchers from the Moscow Institute of Physics and Technology and Lebedev Physical Institute of the Russian Academy of Sciences have designed and tested a prototype cathodoluminescent lamp for general lighting. The new lamp, which relies on the phenomenon of field emission, is more reliable, durable, and luminous than its analogues available worldwide. The development was reported in the Journal of Vacuum Science & Technology B.

Experiment reverses the direction of heat flow

A study used quantum correlations to make heat flow from a colder to a hotter medium without adding external energy, affording a deeper understanding of the second law of thermodynamics.
