Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

Scientists review research on gravitational wave detectors as a historical example of quantum technologies and examine the fundamental research on the connection between quantum physics and gravity.

Light has always been described as an elegant partnership of electric and magnetic fields, yet for nearly two centuries physicists treated the magnetic side as a quiet background player. New ...

Physicists have directly tracked tiny points of darkness in laser light racing faster than light itself, without breaking Einstein’s rules. The new measurements show that these “dark points” in a ...

Fig. 1. (a) Schematic diagram of synchrotron radiation by single-undulator. The temporal spread of the radiation pulse is determined by the spatial distribution of electron bunch. (b) The radiation ...
