Physics news

Water and quantum magnets share critical physics

In physics, things exist in phases, such as solid, liquid and gas states. When something crosses from one phase to another, we talk about a phase transition—like water boiling into steam, turning from liquid to gas.

Fast-spinning black holes narrow the search for dark matter particles

Ultralight bosons are hypothetical particles whose mass is predicted to be less than a billionth the mass of an electron. They interact relatively little with their surroundings and have thus far eluded searches to confirm their existence. If they exist, ultralight bosons such as axions would likely be a form of dark matter, the mysterious, invisible stuff that makes up 85 percent of the matter in the universe.

Little swirling mysteries: New research uncovers dynamics of ultrasmall, ultrafast groups of atoms

Our high-speed, high-bandwidth world constantly requires new ways to process and store information. Semiconductors and magnetic materials have made up the bulk of data storage devices for decades. In recent years, however, researchers and engineers have turned to ferroelectric materials, a type of crystal that can be manipulated with electricity.

Using sound waves to make patterns that never repeat

Mathematicians and engineers at the University of Utah have teamed up to show how ultrasound waves can organize carbon particles in water into a sort of pattern that never repeats. The results, they say, could result in materials called "quasicrystals" with custom magnetic or electrical properties.

New method measures super-fast, free electron laser pulses

New research shows how to measure the super-short bursts of high-frequency light emitted from free electron lasers (FELs). By using the light-induced ionization itself to create a femtosecond optical shutter, the technique encodes the electric field of the FEL pulse in a visible light pulse so that it can be measured with a standard, slow, visible-light camera.

Challenging Einstein's picture of Brownian motion

Around a decade ago, the discovery of Fickian yet non-Gaussian Diffusion (FnGD) in soft and biological materials broke up the celebrated Einstein's picture of Brownian motion. To date, such an intriguing phenomenon is still unexplained due to the major experimental challenges posed by the complex and heterogeneous nature of the underlying materials. To overcome these difficulties, researchers at the University of Naples Federico II (Italy) have now exploited light in place of complex matter to create a heterogeneous environment for particles diffusing in water. The work, now published in Physical Review Letters, stems from a collaboration between the group of Statistical Mechanics of Soft Materials at the Dept. of Chemical, Materials and Production Engineering and the laboratory of Laser Spectroscopy and Optical Manipulation at the Dept. of Physics.

Increasing optical fiber capacity and channel data rates in submarine communication cables

At the bottom of the Atlantic Ocean lies a multitude of cables carrying bundles of optical fibers that support telecommunications between continents. The MAREA cable is considered the gold standard of these transatlantic cables and spans 6,605 km from Virginia Beach, Virginia, U.S. to Bilbao, Spain. It came into service in 2018.

Plasma device designed for consumers can quickly disinfect surfaces

The COVID-19 pandemic has cast a harsh light on the urgent need for quick and easy techniques to sanitize and disinfect everyday high-touch objects such as doorknobs, pens, pencils, and personal protective gear worn to keep infections from spreading. Now scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory and the New Jersey Institute of Technology (NJIT) have demonstrated the first flexible, hand-held, device based on low-temperature plasma—a gas that consists of atoms, molecules, and free-floating electrons and ions—that consumers can quickly and easily use to disinfect surfaces without special training.

Dynamical machine learning accurately reconstructs volume interiors with limited-angle data

Tomographic reconstruction of an object's interior volume from limited angular views is a challenging problem with practical applications in biological imaging, failure analysis of integrated circuits, etc. A team at MIT presents a dynamical machine learning approach for this important problem and shows the method's performance in two problems—tomography under weak and strong scattering conditions. The wide applicability of this technique holds its promise for a number of other challenging inverse problems.

Astronomy and Space news

Study explores extremely luminous infrared galaxy WISEJ0909+0002

An international team of astronomers has investigated an extremely luminous infrared galaxy known as WISEJ090924.01+000211.1 (or WISEJ0909+0002 for short) as part of the eROSITA final equatorial depth survey (eFEDS). Results of this study, published April 6 on the arXiv pre-print server, provide important insights into the properties of this galaxy.
