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…
