When placed under a powerful laser field (i.e., under strong-field ionization), electrons can temporarily cross the so-called quantum tunneling barrier, an energy barrier that they would typically ...

Angles measure the size of a turn in degrees. You can show degrees using the symbol ° after the number of degrees. Imagine two lines acting like the hands of a clock.

These new clocks can measure one of Albert Einstein’s predictions—time dilation due to gravity—on the smallest scale yet. Cutting-edge atomic clocks such as these use neither cesium nor quartz.
