Conduction electrons typically whiz through crystals in broad energy bands. However, some arrangements of atoms conceivably engender so much destructive interference among the electrons’ wave packets ...

Transforming the spectral lines of each element into a musical tone provides a fun tool for teasing out patterns in the electronic structures of atoms. (Top) The visible spectrum of hydrogen consists ...

Experiments at the Large Hadron Collider have revealed a previously unseen nucleus known as antihyperhelium-4. Collisions of heavy ions at the Large Hadron Collider (LHC) at CERN, Switzerland, ...

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 ...

Particle physicists are faced with a growing list of “anomalies”—experimental results that conflict with the standard model but fail to overturn it for lack of sufficient evidence. For their study of ...

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 ...

Jungsang Kim is a professor of Electrical and Computer Engineering, Physics, and Computer Science at Duke University in North Carolina. He leads the Multifunctional Integrated Systems Technology group ...

Structured acoustic fields can pull macroscopic objects towards the source by means of nonconservative forces. Figure 1: (a) Nonconservative pushing force exerted on an object by a plane wave as a ...

Detecting neutrinos offers a new way to monitor the potential bomb materials inside a nuclear reactor, but the technology’s practicality remains uncertain. Neutrino detectors can continuously measure ...

A detailed experimental analysis explains the forces by which a spinning magnet can cause another magnet to levitate in midair. An experiment with off-the-shelf components uses a magnet glued to the ...

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 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 ...
