Physics news

A framework to simulate the same physics using two different Hamiltonians

Researchers at Okinawa Institute of Science and Technology Graduate University in Japan have recently been investigating situations in which two distinct Hamiltonians could be used to simulate the same physical phenomena. A Hamiltonian is a function or model used to describe a dynamic system, such as the motion of particles.

Physicists report definitive evidence how auroras are created

The aurora borealis, or northern lights, that fill the sky in high-latitude regions have fascinated people for thousands of years. But how they're created, while theorized, had not been conclusively proven.

A quantum step to a heat switch with no moving parts

Researchers have discovered a new electronic property at the frontier between the thermal and quantum sciences in a specially engineered metal alloy—and in the process identified a promising material for future devices that could turn heat on and off with the application of a magnetic "switch."

An atom chip interferometer that could detect quantum gravity

Physicists in Israel have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams of atoms. University of Groningen physicist, Anupam Mazumdar, describes how the device could be adapted to use mesoscopic particles instead of atoms. This modification would allow for expanded applications. A description of the device, and theoretical considerations concerning its application by Mazumdar, were published on 28 May in the journal Science Advances.

How coronavirus aerosols travel through lungs

More than 65% of inhaled coronavirus particles reach the deepest region of our lungs where damage to cells can lead to low blood oxygen levels, new research has discovered, and more of these aerosols reach the right lung than the left.

Lighting up ultrafast magnetism in a metal oxide

What happens when very short pulses of laser light strike a magnetic material? A large international collaboration led by the U.S. Department of Energy's (DOE) Brookhaven National Laboratory set out to answer this very question. As they just reported in the Proceedings of the National Academy of Sciences, the laser suppressed magnetic order across the entire material for several picoseconds, or trillionths of a second. Understanding how magnetic correlations change on ultrafast timescales is the first step in being able to control magnetism in application-oriented ways. For example, with such control, we may be able to more quickly write data to memory devices or enhance superconductivity (the phenomenon in which a material conducts electricity without energy loss), which often competes with other states like magnetism.

New COVID-19 model reveals effectiveness of travel restrictions

More strategic and coordinated travel restrictions likely could have reduced the spread of COVID-19 in the early stages of the pandemic. That's according to new research published in Communications Physics. This finding stems from new modeling conducted by a multidisciplinary team of scientists and engineers at Rensselaer Polytechnic Institute.

Infrared imaging leaves invasive pythons nowhere to hide

For more than 25 years, Burmese pythons have been living and breeding in the Florida Everglades, where they prey on native wildlife and disrupt the region's delicate ecosystems. A new study shows that infrared cameras could make it easier to spot these invasive snakes in the Florida foliage, providing a new tool in the effort to remove them.

Artificial intelligence and data mining are being used to measure aerodynamic flows

Developing new ways to measure turbulent flows that are more efficient and reliable is the main objective of the NEXTFLOW research project at the Universidad Carlos III de Madrid (UC3M), funded by an ERC Starting Grant from the European Union. These techniques, which use new developments in artificial intelligence and data mining, can be used to improve the aerodynamics of means of transport and reduce their environmental impact.

Generalizing the measurement postulate in quantum mechanics

The measurement postulate is crucial to quantum mechanics. If we measure a quantum system, we can only get one of the eigenvalues of the measured observable, such as position, energy and so on, with a probability. Immediately after the measurement, the system will collapse into the corresponding eigenstate instantly, known as state collapse. It is argued that the non-cloning theorem is actually a result of the measurement postulate, because non-cloning theorem would also hold in classical physics. The possibility of cloning in classical physics is actually the ability to fully measure a classical system, so that a classical state can be measured and prepared.

Astronomy and Space news

Radio halo detected in a low-mass galaxy cluster

Using the LOw Frequency ARray (LOFAR), European astronomers have carried out radio observations of a low-mass galaxy cluster known as PSZ2G145.92-12.53, dubbed the Ant Cluster. In result, they identified a radio halo—a feature rarely found in low-mass galaxy clusters. The discovery is reported in a paper published May 28 on the arXiv pre-print repository.

Blistering stars in the Universe: Rare insights into the evolution of stars

What happens if a supernova explosion goes off right beside another star? The star swells up which scientists predict as a frequent occurrence in the universe. Supernova explosions are the dramatic deaths of massive stars that are about eight times heavier than the sun.

GMRT measures the atomic hydrogen gas mass in galaxies 9 billion years ago

A team of astronomers from the National Centre for Radio Astrophysics (NCRA-TIFR) in Pune, and the Raman Research Institute (RRI), in Bangalore, has used the Giant Metrewave Radio Telescope (GMRT) to measure the atomic hydrogen gas content of galaxies 9 billion years ago, in the young universe. This is the earliest epoch in the universe for which there is a measurement of the atomic hydrogen content of galaxies. The new result is a crucial confirmation of the group's earlier result, where they had measured the atomic hydrogen content of galaxies 8 billion years ago, and pushes our understanding of galaxies to even earlier in the universe. The new research is published in the 2 June 2021 issue of The Astrophysical Journal Letters.

Capturing water to make the renewable fuels of the future

A successful outcome for the energy transition is very much dependent on the development of alternative fuel solutions that are ultra-clean, renewable, and low in carbon emissions. Fuels that must be replaced include liquefied petroleum gas (LPG) and diesel, which are fuels frequently used in vehicles and in heating. A promising replacement fuel is dimethyl ether (DME). Unlike current fossil fuels, DME leads to low emissions and it can be produced renewably. However, current DME production processes are limited when it comes to producing renewable DME from biomass or CO2, particularly due to problems handling steam in the process. For his Ph.D. research, Jasper van Kampen developed a new process for producing DME, and he defends his thesis on June 4th at the department of Chemical Engineering and Chemistry.
