Zhou and his colleagues considered a well-established technique known as reconstruction of attosecond beating by interference of two-photon transitions (RABBIT). In RABBIT, a train of ...

A proposed model unites quantum theory with classical gravity by assuming that states evolve in a probabilistic way, like a game of chance. Physicists’ best theory of matter is quantum mechanics, ...

The new JWST observatory is revealing far more bright galaxies in the early Universe than anyone predicted, and astrophysicists have more than one explanation for the puzzle. With the JWST observatory ...

Scientists have pinpointed energy-efficient ways to cook al dente pasta and developed an infallible recipe for the perfect cacio e pepe sauce. The study by Toultchinski and Vilgis was inspired by a ...

A “Little Earth Experiment” inside a giant magnet sheds light on so-far-unexplained flow patterns in Earth’s interior. Sketch of outer-core flows derived from data from the Swarm mission (plotted ...

New experiments suggest that superconductivity in twisted bilayer graphene depends on an unconventional electron-pairing mechanism. Figure 1: Two twisted bilayer graphene (TBG) layers stacked one on ...

A new analysis of more than a decade’s worth of observations extends the spectrum of cosmic-ray electrons to unprecedented high energies. Cosmic-ray electrons are high-energy particles that lose ...

Analogs to massless fermions predicted by particle physicists 80 years ago have been found in a crystalline metal and in a photonic crystal. Figure 1: Two possible Fermi surfaces (blue lines) for ...

A new set of equations captures the dynamical interplay of electrons and vibrations in crystals and forms a basis for computational studies. Figure 1: To a first approximation, the vibrations of a ...

Interest in developing batteries based on sodium has recently spiked because of concerns over the sustainability of lithium, which is found in most laptop and electric vehicle batteries. In the 1870 ...

Simulations suggest that optimally placed barriers could boost wind farm performance by as much as 10%. The answer is blowin’. A simulated six-row wind farm with windbreaks (low walls in front of ...

The formation of a black hole from light alone is permitted by general relativity, but a new study says quantum physics rules it out. When light goes dark. According to general relativity, it should ...
