In this work, two quasiparticle excitation energies per particle are calculated analytically for systems with up to N = 7 electrons in both Laughlin and composite fermions (CF) theories by considering the full jellium potential which consists of thre

In a previous work, we reported exact results of energies of the ground state in the fractional quantum Hall effect (FQHE) regime for systems with up to N_{e}=6 electrons at the filling factor ν=1/3 by using the method of complex polar coordinates.

The (2+1)-dimensional Dirac equation for an electron in a constant magnetic field is considered. Exact solutions of this equation along with the corresponding energy spectrum are derived in a concise form. Among these solutions, we noticed that the l

Closed form analytical formulas are derived for both electron–electron and electron–background interaction energies at filling factors ν = 1 and ν = 1 / ( 2 s + 1 ) , integer s. Thus ground state energies are computed at ν = 1 and ν = 1 / 3 f

In this work, quasiparticle energies for systems with N = 3 , 4 , 5 , 6 and 7 electrons are calculated analytically in both Laughlin and composite fermions (CF) theories by considering the electron–electron interaction potential. The exact results

When reviewing the work of Aschieri–Castellani concerning the bicovariant differential calculus on GLq(2), we remarked that a peculiar basis within the space of quantum one-forms over SUq(2) can lead to a new bicovariant differential calculus on SU

A quantum analogue of SL(2) covariance is given. The method consists of defining a bilinear form on SL q(2) co-module, then we ask the defined form to be invariant under SL q(2) co-actions. We showed that the required invariance leads to the standard
