While the theory of composite Fermions (CFs) achieves tremendous successes in understanding the fractional quantum Hall effect and related phenomena, the true nature of CFs is still open to debate. The conventional interpretation, as explicated in Halperin-Lee-Read theory of the composite Fermi-liquid (CFL), regards the CF as an ordinary Newtonian particle. However, the theory suffers from difficulties, which motivate Son to propose that the CF should be a massless Dirac particle. 阅读更多有关 Is the Composite Fermion a Dirac particle?
