Particle-Flux Separation and Quasiexcitations in Quantum Hall Systems

Abstract

The quasiexcitations of quantum Hall systems at the filling factor $\nu =p/(2pq\pm 1)$ are studied in terms of chargeon and fluxon introduced previously as constituents of an electron at $\nu =1/2$. At temperatures $T<T_{\mathrm{PFS}}(\nu )$, the phenomenon so-called particle-flux separation takes place, and chargeons and fluxons are deconfined to behave as quasiparticles. Bose condensation of fluxons justify the (partial) cancellation of external magnetic field. Fluxons describe correlation holes, while chargeons describe composite fermions. They contribute to the resistivity ${\rho }_{xy}=h/(\nu e^2)$ additively.
