Composite fermions are exotic quasi-particles found in interacting 2-D fermion systems at relatively large perpendicular magnetic fields. These quasi-particles, which are composed of an electron and ...

The combined paired and periodic structure of the bubble phase of composite fermions represents an entirely new family of matter. WEST LAFAYETTE, Ind. – Like finding a hidden world, physicists dialing ...

Strong interactions between particles in physical systems can result in various highly correlated ground states. These states and the strong correlations underpinning them have been extensively ...

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 ...

On increasing the applied magnetic field, electrons in a two-dimensional plane in a zinc oxide system go from a gas-like state (bottom) to a liquid state of composite fermions (middle) to a ...

The alternative text for this image may have been generated using AI. We note at the outset that in a system with a parabolic energy-versus-wavevector dispersion, such as AlAs electrons at B=0, the ...

Physicists have made a surprising discovery that the arrangement of atomic nuclei spins helps bring about superconductivity in ytterbium dirhodium disilicide, one of the most-studied materials in a ...

Cooling atoms to ultra-low temperatures reveals the striking differences between fermions and bosons at the quantum level. When the 2001 Nobel Prize for Physics was awarded to Eric Cornell and Carl ...

Like finding a hidden world, physicists dialing up the magnetic field on a semiconducting material have discovered the first in a new family of matter that flowers from the bizarre realm of the ...
