Second-order optical nonlinear effects have received widespread attention from researchers since its first discovery in the 1960s.
Using the Neutron Star Interior Composition Explorer (NICER) onboard the International Space Station (ISS), an international team of astronomers has detected millihertz quasi-periodic oscillations from a low-mass X-ray binary ...
Aerosols transported to the upper troposphere/lower stratosphere (UTLS) region potentially reduce average global surface temperatures and alter atmospheric circulation. Although large volcanic eruptions are rare in recent ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), Chinese astronomers have detected quasi-periodic oscillations (QPOs) in the light curve of HS 2325+8205—a long-period eclipsing dwarf nova. The discovery was detailed ...
Luttinger liquids are usually paramagnetic materials exhibiting non-Fermi liquid behavior, such as molybdenum oxides. These "liquids" and their fascinating properties had so far been only observed in 1D and quasi-1D compounds, ...
Theoretical scientists have used topological mathematics and machine learning to identify a hidden relationship between nano-scale structures and thermal conductivity in amorphous silicon, a glassy form of the material with ...
Imagine a road with two lanes in each direction. One lane is for slow cars, and the other is for fast ones. For electrons moving along a quantum wire, researchers in Cambridge and Frankfurt have discovered that there are ...
Researchers from PSI's Spectroscopy of Quantum Materials group together with scientists from Beijing Normal University have solved a puzzle at the forefront of research into iron-based superconductors: the origin of FeSe's ...
One popular example of chaotic behavior is the butterfly effect—a butterfly may flap its wings in somewhere in the Atlantic Ocean and cause a tornado in Colorado. This remarkable fable illustrates how the extreme sensitivity ...
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have investigated a peculiar emission phenomena exhibited by a pulsar known as PSR B1859+07. Results of the study, published January ...
