Six Flux Composite Fermions

A team of physicists at Purdue University has discovered a new particle, the six-flux composite fermion, expanding the understanding of the fractional quantum Hall effect beyond the known two-flux and four-flux states. This significant finding highlights the critical role of high-quality semiconductor materials and supports the advancement of quantum physics research.

If the fractional quantum Hall regime were a series of highways, these highways would have either two or four lanes. The flow of the two-flux or four-flux composite fermions, like automobiles in this two- to four-flux composite fermion traffic scenario, naturally explains the more than 90 fractional quantum Hall states that form in a large variety of host materials.

Physicists at Purdue University have recently discovered, though, that fractional quantum Hall regimes are not limited to two-flux or four-flux and have discovered the existence of a new type of emergent particle, which they are calling six-flux composite fermion. They have recently published their groundbreaking findings in Nature Communications.    READ MORE...
