Physicists Discover a Quantum State With a New Type of Emergent Particles: 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.

“This occurs in very few instances, like in the fractional quantum Hall regime which we study, for example,” says Csathy. “To explain fractional quantum Hall states, the composite fermion, a very intuitive fundamental building block, comes in different flavors. They can account for a whole subset of the fractional quantum Hall states.

“The GaAs they grow is very special, as the number of imperfections is astonishingly low,” he says. “The combination of low disorder and the ultra-low-temperature measurement expertise in the Csathy lab made this project possible. One reason we were measuring these samples is that very recently the Princeton group has significantly improved the quality of the GaAs semiconductor, as measured by the tiny amounts of defects present.
