New possibilities for detecting Hawking radiation emitted by primordial black holes

While many physicists have predicted the existence of dark matter, a type of matter that does not absorb, reflect or emit light, so far no one has been able to observe it experimentally or determine its fundamental nature. Light primordial black holes (PBHs), black holes the formed in the early universe, are among the most promising dark matter candidates. However, the existence of these black holes has not yet been confirmed.

Common perovskite superfluoresces at high temperatures

A commonly studied perovskite can superfluoresce at temperatures that are practical to achieve and at timescales long enough to make it potentially useful in quantum computing applications. The finding from North Carolina State University researchers also indicates that superfluorescence may be a common characteristic for this entire class of materials.

New research into the spreading of infections reveals need for greater collaboration between biology and physics

Researchers at the Niels Bohr Institute, University of Copenhagen, together with epidemiologist Lone Simonsen from Roskilde University form part of the panel advising the Danish government on how to tackle the different infection-spreading situations we have all seen unfold over the past year. Researchers have modeled the spread of infections under a variety of scenarios, and the Coronavirus has proven to not follow the older models of disease spreading.

New high-speed method for spectroscopic measurements

Researchers at Tampere University and their collaborators have shown how spectroscopic measurements can be made much faster. By correlating polarization to the color of a pulsed laser, the team can track changes in the spectrum of light by simple and extremely fast polarization measurements. The method opens new possibilities to measure spectral changes on a nanosecond time scale over the entire color spectrum of light.

New cold atom source lays groundwork for portable quantum devices

Although quantum technology has proven valuable for highly precise timekeeping, making these technologies practical for use in a variety of environments is still a key challenge. In an important step toward portable quantum devices, researchers have developed a new high-flux and compact cold-atom source with low power consumption that can be a key component of many quantum technologies.

Physicists create platform to achieve ultra-strong photon-to-magnon coupling

A team of scientists from NUST MISIS and MIPT have developed and tested a new platform for realization of the ultra-strong photon-to-magnon coupling. The proposed system is on-chip and is based on thin-film hetero-structures with superconducting, ferromagnetic and insulating layers. This discovery solves a problem that has been on the agenda of research teams from different countries for the last 10 years, and opens new opportunities in implementing quantum technologies. The study was published in the highly ranked journal Science Advances.

PhD student obtains the Higgs mode via dimensional crossover in quantum magnets

In 2013, François Englert and Peter Higgs won the Nobel Prize in Physics for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, which was confirmed through the discovery of the predicted fundamental particle by the A Toroidal LHC Apparatus (ATLAS) and the Compact Muon Solenoid (CMS) experiments at The European Organization for Nuclear Research (CERN)'s Large Hadron Collider in 2012. The Higgs mode or the Anderson-Higgs mechanism (named after another Nobel Laureate Philip W Anderson), has widespread influence in our current understanding of the physical law for mass ranging from particle physics—the elusive "God particle" Higgs boson discovered in 2012 to the more familiar and important phenomena of superconductors and magnets in condensed matter physics and quantum material research.

Chinese superconducting dipole magnet reaches 12 Tesla

The high-field superconducting magnet team of Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences has made progress in a new round of performance tests that ended on June 13. The magnetic field of the dipole magnet developed by the team exceeded 12 Tesla (Tesla) in two apertures at 4.2 K, reaching more than 85% of the critical performance capacity of the superconducting wire. This magnet, including its design, superconducting materials, cables, coils, and related equipment and platform, is based on domestic technologies.

A colorful look at fast-flying particles

The strong nuclear force is one of the four fundamental forces of nature, along with the electromagnetic, gravitational and weak nuclear forces. The branch of particle physics that deals with the strong nuclear force is called quantum chromodynamics (QCD). The term "chromo" refers to the charge in the theory, which is called color (not related to the everyday meaning of the word in terms of visible light). It is important to understand more about QCD, since it gives us a better understanding of nature as a whole and of the universe we occupy. This thesis develops new equations that describe how quantities measured in experiments depend on energy. One such equation describes the energy dependence of the odderon, a particle that has been made famous in international news recently due to its observation at CERN in late 2020. We also use a new method to calculate evolution equations without making the usual assumption that QCD has infinitely many colors, instead of the three colors it has in reality.

Astronomy and Space news

New research adds a wrinkle to our understanding of the origins of matter in the Milky Way

New findings published this week in Physical Review Letters suggest that carbon, oxygen, and hydrogen cosmic rays travel through the galaxy toward Earth in a similar way, but, surprisingly, that iron arrives at Earth differently. Learning more about how cosmic rays move through the galaxy helps address a fundamental, lingering question in astrophysics: How is matter generated and distributed across the universe?

'Pack ice' tectonics reveal Venus' geological secrets

A new analysis of Venus' surface shows evidence of tectonic motion in the form of crustal blocks that have jostled against each other like broken chunks of pack ice. The movement of these blocks could indicate that Venus is still geologically active and give scientists insight into both exoplanet tectonics and the earliest tectonic activity on Earth.

Astronomers inspect the formation of millisecond pulsar PSR J1946+3417

A team of Chinese astronomers has conducted a study aimed at inspecting formation scenarios for the millisecond pulsar PSR J1946+3417. They found that the pulsar was most likely formed as a result of a phase transition. The research was published June 10 on the arXiv pre-print server.

NASA balloon detects California earthquake—next stop, Venus?

Between July 4 and July 6, 2019, a sequence of powerful earthquakes rumbled near Ridgecrest, California, triggering more than 10,000 aftershocks over a six-week period. Seeing an opportunity, researchers from NASA's Jet Propulsion Laboratory and Caltech flew instruments attached to high-altitude balloons over the region in hopes of making the first balloon-borne detection of a naturally occurring earthquake. Their goal: To test the technology for future applications at Venus, where balloons equipped with science instruments could float above the planet's exceedingly inhospitable surface.

Engineers develop inexpensive, scalable method to make metamaterials that manipulate microwave energy

Engineers at Tufts University have developed new methods to more efficiently fabricate materials that behave in unusual ways when interacting with microwave energy, with potential implications for telecommunications, GPS, radar, mobile devices, and medical devices. Known as metamaterials, they are sometimes referred to as "impossible materials" because they could, in theory, bend energy around objects to make them appear invisible, concentrate the transmission of energy into focused beams, or have chameleon like abilities to reconfigure their absorption or transmission of different frequency ranges.

Novel 'smart cement' can be used to build more durable roads and cities

Forces of nature have been outsmarting the materials we use to build our infrastructure since we started producing them. Ice and snow turn major roads into rubble every year; foundations of houses crack and crumble, in spite of sturdy construction. In addition to the tons of waste produced by broken bits of concrete, each lane-mile of road costs the U.S. approximately $24,000 per year to keep it in good repair.
