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 ...

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 ...

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 ...

An instrument on the International Space Station has revealed new information about how the Sun’s magnetic field affects cosmic rays on their way to Earth. The solar modulation of GCRs changes over ...

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 ...

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 ...

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 ...

Figure 1: The shattering of glass is an archetypal fragmentation process. × When a solid object shatters or a liquid drop disintegrates, predicting the outcome seems at first hopelessly difficult. In ...
