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…

Random-phase approximation for the grand-canonical potential of composite fermions in the half-filled lowest Landau level
J. Dietel, Th. Koschny, W. Apel +1
We reconsider the theory of the half-filled lowest Landau level using the Chern-Simons formulation and study the grand-canonical potential in the random-phase approximation (RPA).…
