A universal conformal field theory approach to the chiral persistent currents in the mesoscopic fractional quantum Hall states Original Research Article

We propose a general and compact scheme for the computation of the periods and amplitudes of the chiral persistent currents, magnetizations and magnetic susceptibilities in mesoscopic fractional quantum Hall disk samples threaded by Aharonov–Bohm magnetic field. This universal approach uses the effective conformal field theory for the edge states in the quan
