High-temperature superconductivity : Exploring quadratic electron-phonon coupling
20 juin
A new study published in Physical Review Letters (PRL) explores the potential of quadratic electron-phonon coupling to enhance superconductivity through the formation of quantum bipolarons.
Researchers develop platform to probe, control qubits in silicon for quantum networks
19 juin
The quantum internet would be a lot easier to build if we could use existing telecommunications technologies and infrastructure. Over the past few years, researchers have discovered defects in silicon—a ubiquitous semiconductor material—that could be used to send and store quantum information (…)
Study reveals material erosion and deposition in fusion reactors
19 juin
Researchers led by Prof. Luo Guangnan from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences have made an important discovery about how materials break down and mix on the surfaces inside the experimental advanced superconducting tokamak (EAST). They found that (…)
Upgraded advanced photon source sees first X-ray light for science
19 juin
After a year of installation and commissioning, the new electron storage ring at the heart of the Advanced Photon Source—powered by a world’s first injection technique—is ready for business.
Generation of intense terahertz waves with a magnetic material
19 juin
Terahertz waves are being intensely studied by researchers around the world seeking to understand the "terahertz gap." Terahertz waves have a specific frequency that puts them somewhere between microwaves and infrared light. This range is referred to as a "gap" because much (…)
Discovery of one-dimensional topological insulator for qubits, other technology
19 juin
A joint research team that included members from Tohoku University has unveiled a new topological insulator (TI), a unique state of matter that differs from conventional metals, insulators, and semiconductors.
The design of a photonic alloy with topological properties
19 juin
Photonic alloys, alloy-like materials combining two or more photonic crystals, are promising candidates for the development of structures that control the propagation of electromagnetic waves, also known as waveguides. Despite their potential, these materials typically reflect light back in (…)
New theory broadens phase transition exploration
18 juin
In a paper recently published in Physical Review Letters, Los Alamos National Laboratory researchers offer a new theory that predicts defect density across a variety of phase transitions. The research opens new routes for the exploration of defect formation in fields such as materials science, (…)
Physicists combine multiple Higgs boson pair studies and discover clues about the stability of the universe
18 juin
Remember how difficult it was to find one Higgs boson ? Try finding two at the same place at the same time. Known as di-Higgs production, this fascinating process can tell scientists about the Higgs boson self-interaction.
New method enhances X-ray microscopy for detecting tiny defects
18 juin
X-ray microscopes are essential for examining components and materials because they can be used to detect changes and details in the material. Until now, however, it has been difficult to detect small cracks or tiny inclusions in the images.
