Unconventional superconductor acts the part of a promising quantum computing platform

Scientists on the hunt for an unconventional kind of superconductor have produced the most compelling evidence to date that they've found one. In a pair of papers, researchers at the University of Maryland's (UMD) Quantum Materials Center (QMC) and colleagues have shown that uranium ditelluride (or UTe2 for short) displays many of the hallmarks of a topological superconductor—a material that may unlock new ways to build quantum computers and other futuristic devices.

Emergent magnetic monopoles isolated using quantum-annealing computer

Using a D-Wave quantum-annealing computer as a testbed, scientists at Los Alamos National Laboratory have shown that it is possible to isolate so-called emergent magnetic monopoles, a class of quasiparticles, creating a new approach to developing "materials by design."

Producing memory from speckle patterns

A team of researchers has developed a way to significantly increase the memory of speckle patterns, the very complex patterns that result from shining a laser light onto an opaque sheet, such as paper, biological tissue, or fog.

Physicists discover simple propulsion mechanism for bodies in dense fluids

A team of researchers from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), the University of Liège and the Helmholtz Institute Erlangen-Nürnberg for Renewable Energy have developed a micro-swimmer that appears to defy the laws of fluid dynamics: Their model, consisting of two beads connected by a linear spring, is propelled by completely symmetrical oscillations. The scallop theorem states that this cannot be achieved in fluid microsystems. The findings have now been published in the academic journal Physical Review Letters.

The paradox of a free-electron laser without the laser

A new way of producing coherent light in the ultra-violet spectral region, which points the way to developing brilliant table-top X-ray sources, has been produced in research led at the University of Strathclyde.

A simplified method for calibrating optical tweezers

Measurements of biomechanical properties inside living cells require minimally-invasive methods. Optical tweezers are particularly attractive as a tool. They use the momentum of light to trap and manipulate micro- or nanoscale particles. A team of researchers led by Prof. Dr. Cornelia Denz from the University of Münster (Germany) has now developed a simplified method to perform the necessary calibration of the optical tweezers in the system under investigation. Scientists from the University of Pavia in Italy were also involved. The results of the study have been published in the journal Scientific Reports.

Future information technologies: Topological materials for ultrafast spintronics

The laws of quantum physics rule the microcosm. They determine, for example, how easily electrons move through a crystal and thus whether the material is a metal, a semiconductor or an insulator. Quantum physics may lead to exotic properties in certain materials: In so-called topological insulators, only the electrons that can occupy some specific quantum states are free to move like massless particles on the surface, while this mobility is completely absent for electrons in the bulk. What's more, the conduction electrons in the "skin" of the material are necessarily spin polarized, and form robust, metallic surface states that could be utilized as channels in which to drive pure spin currents on femtosecond time scales (1 fs = 10-15 s).

Watching the ultrafast dance moves of a laser plasma

Great leaps in science and technology have been propelled by recent advances in seeing fast evolving physical phenomena, as they happen. Femtosecond lasers from the infrared to the X-ray region have enabled us to 'watch', in real time, atoms dance in molecules and solids on femtosecond and picosecond timescales. Watching such fascinating motions not just in real time, but at the spatial locations where they happen, is a bigger challenge.

Noninvasive, label-free optical method visualizes deep, cellular brain disease in vivo

Using long wavelength near-infrared light, scientists at UC Davis developed a label-free microscopy approach that achieves a unique combination of deep, high resolution, and minimally invasive brain imaging. The technique images neurons and axonal myelination across the mouse neocortex and some sub-cortical regions, through the thinned skull. Now studies of brain disease can be conducted deep in the mouse brain through a minimally invasive and simple surgical preparation.

Galactic fireworks: New ESO images reveal stunning features of nearby galaxies

A team of astronomers has released new observations of nearby galaxies that resemble colorful cosmic fireworks. The images, obtained with the European Southern Observatory's Very Large Telescope (ESO's VLT), show different components of the galaxies in distinct colors, allowing astronomers to pinpoint the locations of young stars and the gas they warm up around them. By combining these new observations with data from the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, the team is helping shed new light on what triggers gas to form stars.

Big bang: How we are trying to 'listen' to it, and the new physics it could unveil

Exactly what happened at the beginning of the universe, 14 billion years ago, is one of the greatest mysteries in physics—there's no simple way to probe it. That's because, in its early stages, the universe was filled with a dense plasma—a gas made out of charged particles including electrons and protons (particles that comprise the atomic nucleus alongside neutrons). Photons (particles of light) were trapped in the mix, bouncing off the other particles furiously, with no way to escape.

Activity discovered on largest comet ever found

A newly discovered visitor to the outer edges of our solar system has been shown to be the largest known comet ever, thanks to the rapid response telescopes of Las Cumbres Observatory. The object, which is named Comet C/2014 UN271 Bernardinelli-Bernstein after its two discoverers, was first announced on Saturday, June 19th, 2021. C/2014 UN271 was found by reprocessing four years of data from the Dark Energy Survey, which was carried out using the 4-m Blanco telescope at Cerro Tololo Inter-American Observatory in Chile between 2013 and 2019. At the time of the announcement, there was no indication that this was an active world. Anticipation was immediately high among astronomers. C/2014 UN271 was inbound from the cold outer reaches of the solar system, so rapid imaging was needed to find out: when would the big new-found world start to show a comet's tail?

Their groundbreaking findings are published in the renowned journal Nature Electronics.
