...a team of physicists has taken a key step in fulfilling graphene's promise as a hotbed of exotic physics by showing that the electrons within it can team up to behave like particles with a fraction of the electron's charge. The effect is called the fractional quantum Hall effect, and it's an esoteric embellishment of an already esoteric phenomenon known as the Hall effect.The Hall effect was what led to the breakup, and obscurity for Oates as well as Hall. Thanks neverdem.
Ah, so that’s why it’s called the quantum Hall effect ... the missing Oates.
