Physics Breakthrough: Researchers Overcome Long-Standing Limitation of First Law of Thermodynamics

Physicists at West Virginia University have overcome a long-standing limitation of the first law of thermodynamics.

Paul Cassak, a professor and associate director of the Center for KINETIC Plasma Physics at West Virginia University, and Hasan Barbhuiya, a graduate research assistant in the Department of Physics and Astronomy, are investigating the conversion of energy in superheated plasmas in space. Funded by the National Science Foundation, their findings, published in the Physical Review Letters journal, are set to revolutionize the understanding of how plasmas in space and labs are heated and could have far-reaching implications in physics and other sciences.

A robust quantum memory that stores information in a trapped-ion quantum network

Researchers at University of Oxford have recently created a quantum memory within a trapped-ion quantum network node. Their unique memory design, introduced in a paper in Physical Review Letters, has been found to be extremely robust, meaning that it could store information for long periods of time despite ongoing network activity.

“We are building a network of quantum computers, which use trapped ions to store and process quantum information,” Peter Drmota, one of the researchers who carried out the study, told Phys.org. “To connect quantum processing devices, we use emitted from a single atomic ion and utilize between this ion and the photons.”

Trapped ions, charged atomic particles that are confined in space using , are a commonly used platform for realizing quantum computations. Photons (i.e., the particles of light), on the other hand, are generally used to transmit quantum information between distant nodes. Drmota and his colleagues have been exploring the possibility of combining trapped ions with photons, to create more powerful quantum technologies.

Study investigates diffuse emission from the Cigar Galaxy

Using NASA’s Chandra spacecraft, an international team of astronomers has performed X-ray observations of the Cigar Galaxy. Results of the observational campaign, presented March 16 on the pre-print repository arXiv, deliver crucial information regarding diffuse emission from this galaxy.

Discovered in 1,774, Cigar Galaxy (Messier 82, or M82) is a located some 11.73 million away in the constellation Ursa Major. It has a size of about 40,800 light years and is one of the closest starburst to Earth.

Observations of the Cigar Galaxy have found that it experiences a large-scale galactic wind at various wavelengths, for instance, in hard X-rays above a few keV. This superwind appears to be concentrated in the galaxy’s two high surface brightness regions or clumps, and is fueled by energy released by supernovae within the clumps that occur at a rate of about one every ten years. Previous Chandra studies of this galaxy have detected bright X-ray binaries that dominate the hard X-ray band and revealed that there is residual diffuse emission surrounding the starburst disk.

The Periodic Table Has Been Sonified And Every Element Sounds Unique

The unique radiation emitted by heated or electrified elements has been converted into sound, enabling us to hear the distinctive chord each element produces. Although the idea has been tried before, advances in technology have now made it possible for a far more complete and subtle sonification of the periodic table.

When elements are energized electrons can jump to higher energy levels. Eventually, they return to their ground state, releasing a photon in the process. The wavelength of the photon depends on the size of the energy gap between the excited state and the ground state – more energy produces higher frequency/shorter wavelength light.

The discovery of this fact has proven crucial for our understanding of the universe. We can identify the elements in a star billions of light-years away from the distinctive wavelengths it emits, known as its emission spectra. At the American Chemical Society’s Spring Conference over the weekend, the University of Indiana’s W. Walker Smith demonstrated the result if every element’s electromagnetic spectrum is converted to sound.

NASA’s Artemis astronauts will likely 3D print batteries on the Moon

The space agency teamed up with university researchers to investigate the best methods for 3D printing space batteries.

A team of researchers at the University of Texas at El Paso (UTEP) and Youngstown State University (YSU) are collaborating to develop 3D-printed batteries for future lunar astronauts.
