Direct observation of composite fermions and their fully spin-polarized Fermi sea near ν=5/2

The enigmatic even-denominator fractional quantum Hall state at Landau level filling factor \nu=5/2 is arguably the most promising candidate for harboring Majorana quasi-particles with non-Abelian statistics and thus of potential use for topological quantum computing. The theoretical description of the \nu=5/2 state is generally believed to involve a topological p-wave... Show more
