Emergence of Dirac Composite Fermions: Dipole Picture
Guangyue Ji, Junren Shi
Composite fermions (CFs) are the particles underlying the novel phenomena observed in partially filled Landau levels. Both microscopic wave functions and semi-classical dynamics su…

Asymmetry of the Geometrical Resonances of Composite Fermions
Guangyue Ji, Junren Shi
We propose an experiment to test the uniform-Berry-curvature picture of composite fermions. We show that the asymmetry of geometrical resonances observed in a periodically modulate…

Berry phase of the composite Fermi-liquid
Guangyue Ji, Junren Shi
We derive the definition of the Berry phase for the adiabatic transport of a composite fermion (CF) in a half-filled composite Fermi-liquid (CFL). It is found to be different from…
