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 ...

Experiments show that bundling of individual strands of an important protein polymer can occur through capillary forces, not just through molecular binding. Separated at birth. The chromosomes (blue) ...

John F. Barry is an experimental physicist currently at MIT Lincoln Laboratory. He received his Ph.D. from Yale University in the group of Dave DeMille, where he worked to demonstrate the first laser ...

Experiments successfully capture signatures of a discrete time crystal phase in an open, quantum many-body system. Time crystals can break continuous symmetry when realized in a time-independent ...

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 ...

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 ...

Gravitational waves emitted by the merger of two black holes have been detected, setting the course for a new era of observational astrophysics. Figure 1: Numerical simulations of the gravitational ...

Figure 1: Will two objects fall at the same rate in a vacuum? Galileo was the first to test this equivalence principle, and he was followed by many others, including the Apollo astronauts. Now, the ...

The creation of modern quantum mechanics was a messy business in which many of the participants did not grasp the significance of their own discoveries. The wave nature of electrons is revealed in ...

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 ...

Researchers use a laser to excite and precisely measure a long-sought exotic nuclear state, paving the way for precise timekeeping and ultrasensitive quantum sensing. Figure 2: The precision of ...

In 1935, Albert Einstein, Boris Podolsky, and Nathan Rosen (EPR) wrote a now famous paper questioning the completeness of the formalism of quantum mechanics. Rejecting the idea that a measurement on ...
