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…
Time domain analysis of dynamical switching in a Josephson junction
Joachim Sjostrand, Jochen Walter, David Haviland +2
We have studied the switching behaviour of a small capacitance Josephson junction both in experiment, and by numerical simulation of a model circuit. The switching is a comples pro…
Half-Filled Lowest Landau Level on a Thin Torus
Emil J. Bergholtz, Anders Karlhede
We solve a model that describes an interacting electron gas in the half-filled lowest Landau level on a thin torus, with radius of the order of the magnetic length. The low energy…
