Study unveils gapless ground state in an archetypal quantum kagome

At low enough temperatures, magnetic systems typically become solid crystals. A renowned phenomenon through which this happens is ferromagnetism, occurring when all elementary moments or spins interact at the atomic scale (i.e., the so-called Heisenberg interaction) and align in one direction. Ferromagnetism underpins the functioning of several everyday objects, including compasses, fridge magnets and hard drives.

Model simulator helps researchers map complex physics phenomena

To understand the behavior of quantum particles, imagine a pinball game—but rather than one metal ball, there are billions or more, all ricocheting off each other and their surroundings.

Leap in performance sees hollow-core fiber technology close in on mainstream optical fiber

Researchers from the Zepler Institute for Photonics and Nanoelectronics at the University of Southampton have demonstrated a new leap in hollow-core fiber performance, underlining the technology's potential to soon eclipse current optical fibers.

Precision mirrors poised to improve sensitivity of gravitational wave detectors

Researchers have developed a new type of deformable mirror that could increase the sensitivity of ground-based gravitational wave detectors such as the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO). Advanced LIGO measures faint ripples in space time called gravitational waves, which are caused by distant events such as collisions between black holes or neutron stars.

New telescope design could capture distant celestial objects with unprecedented detail

Researchers have designed a new camera that could allow hypertelescopes to image multiple stars at once. The enhanced telescope design holds the potential to obtain extremely high-resolution images of objects outside our solar system, such as planets, pulsars, globular clusters and distant galaxies.

An advance in molecular moviemaking shows how molecules respond to two photons of light

Over the past few years, scientists have developed amazing tools—"cameras" that use X-rays or electrons instead of ordinary light ¬- to take rapid-fire snapshots of molecules in motion and string them into molecular movies.

Method of angular momentum multiplexing and demultiplexing for high-capacity optical communications

Optical multiplexing and demultiplexing utilizing the intrinsic physical properties of light has played a crucial role in high-capacity data storage and high-speed communications.

Distortion isn't a drag on fluid-straddling particles

Some intriguing physics can be found at the interfaces between fluids, particularly if they are straddled by particles like proteins or dust grains. When placed between un-mixable fluids such as oil and water, a variety of processes, including inter-molecular interactions, will cause the particles to move around. These motions are characterised by the drag force experienced by the particles, which is itself thought to depend on the extent to which they distort fluid interfaces. So far, however, experiments investigating the intriguing effect haven't yet fully confirmed the influence of this distortion. In new research published in EPJ E, a team led by Jean-Christophe Loudet at the University of Bordeaux, France, showed that the drag force experienced by fluid-straddling particles is less affected by interface distortion than previously believed.

The imitation game: Scientists describe and emulate new quantum state of entangled photons

A research team from ITMO University, with the help of colleagues from MIPT (Russia) and Politecnico di Torino (Italy), has predicted a novel type of topological quantum state of two photons. Scientists have also applied a new, affordable experimental method for testing this prediction. The method relies on an analogy: Instead of expensive experiments with quantum systems of two or more entangled photons, the researchers have used resonant electric circuits of higher dimensionality described by similar equations. The obtained results can be useful for the engineering of optical chips and quantum computers without the need for expensive experiments. The research was published in Nature Communications.

Frozen-planet states in exotic helium atoms

Exotic subatomic particles that are like 'normal' particles apart from one, opposite, property—such as the positron, which is like an electron but positively rather than negatively charged—are collectively known as antimatter. Direct studies of collisions between particles of matter and those of antimatter using giant facilities such as those at CERN can advance our understanding of the nature of matter. A new study by Tasko Grozdanov from the University of Belgrade in Serbia and Evgeni Solov'ev from the Institute of Nuclear Research near Moscow in Russia has mapped the energy levels of an exotic form of helium produced in this way. This work, which is published in EPJ D, has been described by one commentator as '... a new jewel in the treasure of scientific achievements in atomic physics theory".

Technology news

A human-like planner that allows robots to reach for objects in cluttered environments

While research in the field of robotics has led to significant advances over the past few years, there are still substantial differences in how humans and robots handle objects. In fact, even the most sophisticated robots developed so far struggle to match the object manipulation skills of the average toddler. One particular aspect of object manipulation that most robots have not yet mastered is reaching and grasping for specific objects in a cluttered environment.

Stanford engineers create shape-changing, free-roaming soft robot

Advances in soft robotics could someday allow robots to work alongside humans, helping them lift heavy objects or carrying them out of danger. As a step toward that future, Stanford University researchers have developed a new kind of soft robot that, by borrowing features from traditional robotics, is safe while still retaining the ability to move and change shape.

Shedding light on optimal materials for harvesting sunlight underwater

There may be many overlooked organic and inorganic materials that could be used to harness sunlight underwater and efficiently power autonomous submersible vehicles, report researchers at New York University. Their research, publishing March 18 in the journal Joule, develops guidelines for optimal band gap values at a range of watery depths, demonstrating that various wide-band gap semiconductors, rather than the narrow-band semiconductors used in traditional silicon solar cells, are best equipped for underwater use.

Can humans and artificial intelligence come together to predict the future?

It could be argued that scientists create superpowers in their labs. If Aram Galstyan, director of the Artificial Intelligence Division at the USC Viterbi Information Sciences Institute (ISI) had to pick just one superpower, it would be the ability to predict the future. What will be the daily closing price of Japan's Nikkei 225 index at the end of next week? How many 6.0 or stronger earthquakes will occur worldwide next month? Galstyan and a team of researchers at USC ISI are building a system to answer such questions.

Cross-technology communication in the Internet of Things significantly simplified

Whether networked vehicles that warn of traffic jams in real time, household appliances that can be operated remotely, "wearables" that monitor physical activity, or industrial plants that detect possible production errors in time and notify technical support, the number of intelligent products that communicate wirelessly with other devices in the Internet of Things (IoT) age has increased rapidly in recent years. However, not all of these devices are compatible with each other because they use different wireless technologies such as Wi-Fi, Bluetooth (low energy) or ZigBee, depending on the requirements and application. More than that, many devices often have the same radio frequencies and interfere with each other. This delays data transmission, data can be lost, energy consumption increases and battery life decreases.

New research improves drone detection for increased public safety

Unmanned aerial vehicles (UAV), commonly known as drones, are widely used in mapping, aerial photography, rescue operations, shipping, law enforcement, agriculture, among other things. Despite great potential for improving public safety, use of drones can also lead to very undesirable situations, such as privacy and safety violations, or property damage. There is also the highly concerning matter of drones being harnessed to carry out terrorist attacks, which means a threat to public safety and national security.
