Laser blasts drive the fastest logic gates ever

Simultaneous laser pulses (red and blue) generate a burst of real and virtual charge carriers in graphene that is absorbed by gold metal to produce a net current. “We demonstrated the role of virtual and real charge carriers in laser-induced currents, and this opened the way for the creation of ultrafast logic gates,” says Ignacio … Read more

New research reveals how liars are exposed through distraction

Credit: Pixabay/CC0 Public Domain A new method of lie detection shows that it is easier to identify lie detectors who are given multiple tasks during interviews. It is well documented that lying during interviews consumes more cognitive energy than telling the truth. A new study by the University of Portsmouth found that investigators who used … Read more

Researchers find a way to form diodes from superconductors

Credit: Unsplash/CC0 Public Domain A group of researchers from Pisa, Jyväskylä, San Sebastian and MIT have shown how a heterogeneous structure consisting of superconductors and magnets can be used to generate unidirectional current such as that found in semiconductor diodes. However, these new superconducting diodes work very efficiently low temperatures than their semiconductor counterparts, and … Read more

A 10-minute meditation can help de-polarize Brexit

One particle on two paths: Quantum physics is right

The laboratory at ILL in Grenoble Laurent Thion, ILL. Credit: Vienna University of Technology The double slit experiment is the best known and perhaps the most important experiment in quantum physics: individual particles are fired against a wall of two holes, behind which the detector measures where the particles are arriving. This shows that the … Read more

Researchers reveal the story of the origin of carbon 12, an essential building block of life

This computer simulation shows the structures of carbon-12 in the unstable, excited Hoyle state and as a stable ground state, the substance of life. Credit: James Fare/Iowa State University With the help of the world’s most powerful supercomputer and new artificial intelligence techniques, an international team of researchers has theorized how extreme conditions in stars … Read more

The first research and study on the synthesis of materials in the terapascal range

The structures and properties of materials under extremely high pressures and temperatures are still largely “terra-unknown”. Professor Leonid Dobrovinsky and his research partners use a laser-heated two-stage diamond anvil cell they built to synthesize materials in the terapascal (1,000 gigapascal) range. In situ single crystal X-ray diffraction is used for simultaneous structural characterization of materials. … Read more

The strongest gravity in the early universe may solve a cosmic dilemma

The inflationary era that caused the universe to expand rapidly in its first moments may be linked to the modern age of dark energy, thanks to a ghostly component of the universe that changes the force of gravity as the universe evolves, a New Age physicist suggests. paper. The traditional approach to understanding gravity Includes … Read more

God, Dark Matter and Fallen Cats: A Conversation with 2022 Templeton Prize Winner Frank Wilczek

Frank Wilczek, a theoretical physicist and Nobel Prize-winning author, has been announced as the recipient of the 2022 Templeton Prize, which is valued at more than $1.3 million. The annual award honors those “who harness the power of science to explore the deepest questions of the universe and the place and purpose of humankind,” according … Read more
