Novel insights on the interplay of electromagnetism and the weak nuclear force

Outside atomic nuclei, neutrons are unstable particles, with a lifetime of about fifteen minutes. The neutron disintegrates due to the weak nuclear force, leaving behind a proton, an electron, and an antineutrino. The weak ...

An optical method to polarize free electrons in a laboratory setting

Polarized electrons are electrons in which spins have a "preferred" orientation or are preferentially oriented in a specific direction. The realization of these electrons has notable implications for physics research, as ...

Could dark photon dark matter be directly detected using radio telescopes?

Dark matter, matter in the universe that does not emit, absorb or reflect light, cannot be directly detected using conventional telescopes or other imaging technologies. Astrophysicists have thus been trying to identify alternative ...

Curved spacetime in a quantum simulator

The theory of relativity works well when you want to explain cosmic-scale phenomena—such as the gravitational waves created when black holes collide. Quantum theory works well when describing particle-scale phenomena—such ...

Neutron star's X-rays reveal 'photon metamorphosis'

A "beautiful effect" predicted by quantum electrodynamics (QED) can explain the puzzling first observations of polarized X-rays emitted by a magnetar—a neutron star featuring a powerful magnetic field, according to a Cornell ...
