One-Dimensional Theory of the Quantum Hall System
Emil J. Bergholtz, Anders Karlhede
We consider the lowest Landau level on a torus as a function of its circumference . When , the ground state at general rational filling fraction is a crystal with 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…
Density Matrix Renormalization Group Study of a Lowest Landau Level Electron Gas on a Thin Cylinder
Emil J. Bergholtz, Anders Karlhede
We investigate the ground state properties of a two-dimensional electron gas in the lowest Landau level using the Density Matrix Renormalization Group. The electron gas is confined…
