New twist in quest to develop understanding of time crystalline behavior

NOVEMBER 21, 2019 by University of Exeter The quest to develop the understanding for time crystalline behaviour in quantum systems has taken a new, exciting twist. Physics experts from the Universities of Exeter, Iceland, and ITMO University in St. Petersburg, have revealed that the existence of genuine time crystals for closed quantum systems is possible. Different […]

Photosynthesis seen in a new light by rapid X-ray pulses

“This work is so important, as it shows the first proof of concept of megahertz serial crystallography with one of the largest and most complex membrane proteins in photosynthesis: Photosystem I” says Fromme.  NOVEMBER 8, 2019 by Richard Harth, Arizona State University The ability to transform sunlight into energy is one of Nature’s more remarkable feats. […]

Physicists provide a new view on how liquids behave with other materials

When a liquid such as water is repelled from a solid substrate, the drop created exhibits a large contact angle. OCTOBER 15, 2019 by University of Bristol Using a range of theoretical and simulation approaches, physicists from the University of Bristol have shown that liquids in contact with substrates can exhibit a finite number of classes […]

Less than zero energy – quantum vacuum

by Vienna University of Technology Energy is a quantity that must always be positive—at least that’s what our intuition tells us. If every single particle is removed from a certain volume until there is nothing left that could possibly carry energy, then a limit has been reached. Or has it? Is it still possible to extract […]

MIT graduate student slices microwave pulses to test advanced accelerators

Julian Picard: Chopping microwaves, sharpening instincts Paul Rivenberg | MIT | Plasma Science and Fusion Center August 12, 2019 “Looking through microscopes has never been my thing,” says Julian Picard. As a graduate student in the Department of Physics, Picard works with the invisible world of particles and electromagnetic waves every day, yet he is motivated […]
