In a first, US researchers have observed fractional excitons, a new class of quantum particles, that were only theoretically ...

In the fractional quantum Hall effect, these steps become even more peculiar, increasing by only fractional amounts—carrying a fraction of an electron's charge.

In 1998, a Nobel Prize was awarded for the discovery and understanding of the fractional quantum Hall effect, which suggested that flatland particles could have fractional charges. The journey ...

In quantum physics, subatomic particles behave strangely—they can be in two places simultaneously, move through solid objects, and communicate instantly over long distances. Scientists are studying ...

exhibiting quantized values that are integral or fractional multiples of e²/h, where e is the elementary charge and h is Planck’s constant. One of the most remarkable aspects of the Quantum Hall ...

In particular, the research team discovered a new electronic state called "1/3 fractional quantum Hall state." This state is unique because electrons move as if in three parts, which is completely ...
