Quantum Hall effect
The SI system underwent a revision that fixed exact values of fundamental constants related to the quantum Hall effect, further solidifying its importance in precise electrical measurements.
|
| 2012 | Researchers successfully created persistent spin helices of synchronized electrons that lasted over a nanosecond, a 30-fold increase from previous experiments, exceeding a modern processor clock cycle duration. |
