Measurements indicate that intense x-ray pulses can change the electronic structure of a material on femtosecond timescales, a finding that could improve imaging of light–matter interactions.

A detailed experimental analysis explains the forces by which a spinning magnet can cause another magnet to levitate in midair.

The flow field generated by swimming bacteria drives a long-range attractive force felt by passive objects much larger than the swimmers themselves.

The 2023 Nobel Prize in Physics honors the field of attosecond physics, which offers a nonblurry view of the fast-moving electrons around atoms and molecules.

A crystalline reflective coating being considered for future gravitational-wave detectors exhibits peculiar noise features at cryogenic temperatures.

The early failure of thin-walled cones under compression was thought to arise mainly from the presence of imperfections. A new model suggests otherwise.  

The envelopes for this year’s Nobel Prize winners are already sealed, but a survey of physicists offers ideas on future discoveries that are shoo-ins for Nobel recognition.

By using a pair of offset beams, researchers are able to generate femtosecond UV pulses that can be aimed directly into a target as a spectroscopic probe.

Researchers have turned an optical lattice into a ratchet that moves atoms from one site to the next.
