Physicists have forced light to behave like electrons trapped in a magnetic field, reproducing the quantum Hall effect with photons for the first time. The experiment, carried out on an optical fiber ...

Physicists have taken quantum strangeness to an extraordinary new level by measuring light across 37 dimensions. Their groundbreaking experiment pushes quantum mechanics beyond classical expectations, ...

Attosecond pulses enable sub-femtosecond studies of ultrafast electron dynamics. Since 2001, pulse durations have shortened ...
