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 ...

Whether a droplet hitting a solid surface flattens smoothly or forms a ragged splash depends on the gas surrounding it. When a liquid drop hits a solid surface, like a raindrop hitting pavement, it ...

The mass-and-spring-like behavior of a water droplet helps explain its ability to seal the leaky pipe from where it came. Liquid leaking from a small hole in the side of a vertical pipe transitions ...

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 ...

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 ...

Meera Parish is a professor in theoretical physics at Monash University in Australia. Since obtaining her PhD from the University of Cambridge, UK, she has been a PCTS postdoctoral fellow at Princeton ...

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 ...

The demonstration that ions can be precisely manipulated in a trap containing integrated photonics paves the way for a large-scale trapped-ion quantum processor. Figure 1: Mordini and colleagues ...

A new theory related to the second law of thermodynamics describes the motion of active biological systems ranging from migrating cells to traveling birds. Figure 1: A biological cell (black outline) ...

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, ...

Two studies find that fundamental quantum constraints rule out a previously proposed neutrino-laser scheme. In last year’s proposal of a neutrino laser, the researchers sought to exploit the same ...

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 ...
