Exclusion statistics for quantum Hall states in Tao-Thouless limit
Mikael Kardell, Anders Karlhede
We consider spin-polarized abelian quantum Hall states in the Tao-Thouless limit, {\it ie} on a thin torus. For any filling factor a well-defined sector of low-energy state…
Tao-Thouless Revisited
T. H. Hansson, A. Karlhede
It is now established that the state proposed by Tao and Thouless for the fractional quantum Hall effect in 1983, shortly after Laughlin's work, is the ground state in the so-calle…
Properties of the doped spin 3/2 Mott insulator near half filling
Stellan Ostlund, A. Karlhede, T. H. Hansson
We develop an exact generalized Bogoliubov transformation for the spin 3/2 Hubbard model with large anti-Hunds rule coupling near half filling. Since our transformation is unitary,…
Solitons and Quasielectrons in the Quantum Hall Matrix Model
T. H. Hansson, J. Kailasvuori, A. Karlhede +1
We show how to incorporate fractionally charged quasielectrons in the finite quantum Hall matrix model.The quasielectrons emerge as combinations of BPS solitons and quasiholes in a…
Charge and Current in the Quantum Hall Matrix Model
T. H. Hansson, J. Kailasvuori, A. Karlhede
We extend the quantum Hall matrix model to include couplings to external electric and magnetic fields. The associated current suffers from matrix ordering ambiguities even at the c…
