Exact Symmetries of Electron Interactions in the Lowest Landau Level
M. Eliashvili, Z. F. Ezawa, G. Tsitsishvili
Considering the system of interacting electrons in the lowest Landau level we show that the corresponding four-fermion Hamiltonian is invariant with respect to the local area-prese…

Phase Transitions in the Bilayer Quantum Hall Effect
N. Kumada, D. Terasawa, Y. Shimoda +6
We measured the magnetoresistance of bilayer quantum Hall (QH) effects at the fractional filling factor by changing the total electron density and the density difference be…

Field Theory of Quantum Hall Effects, Composite Bosons, Vortices and Skyrmions
Z. F. Ezawa
A field theory of quantum Hall effects is constructed based on the \CB picture. It is tightly related with the microscopic wave-function theory. The characteristic feature is that…
