Path Integral for Composite Fermions in the Half-Filled Lowest Landau Level
W. Weller, J. Dietel, Th. Koschny +1
We consider electrons in two dimensions in a strong magnetic field at half filling of the lowest Landau level using the Chern-Simons approach. Starting from a lattice Hamiltonian f…

A comparison of FQHE quasi-electron trial wave functions on the disk
M. Kasner, W. Apel
The various proposals for FQHE quasi-electron trial wave functions are reconsidered. In a short-range model for the electronic interaction, the energy expectation values of four di…
