When intense quantum light knocks electrons out of atoms, the statistics of the light can be transferred to the electrons. Strong-field ionization—a process in which intense laser light strips ...

Pairing superconducting qubits with microwave cavities could reduce the hardware requirements for quantum simulations of fundamental physics. Performing simulations of quantum systems on an ordinary ...

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 ...

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 ...

No photos of the future. Since the laws of physics could allow time to run forward or backward, it’s not obvious why time as we perceive it must move in the same direction as that required by ...

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 ...

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 ...

In its superconducting state, an exotic metal harbors charge carriers that appear to have 4 and 6 times the charge of a single electron, suggesting the formation of Cooper-pair “molecules.” Figure 1: ...

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 ...

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 ...

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 ...

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 ...
