Outline of Final Research Achievements

We investigate Josephson tunneling in the bilayer quantum Hall system at the total filling ν = 1. We show the existence of the critical current for the tunneling current to be coherent and dissipationless. Our results explain recent experiments.
We were going to experiment on the AC Josephson effect, but the sample was defective, and we had to prepare a new sample. During this time, we went ahead with a study of the huge longitudinal resistance (HLR) state by increasing the electric current at the filling ν = 2/3 quantum Hall state. We obtained the following new experimental results: 1) the HLR state exhibits the negative temperature dependence; 2) the HLR state is formed by AC current, not by DC current; 3) the Hall resistance retains the plateau shape even in the HLR state; and 4) the Hall resistance value shifts depending on the filling value position of the current pumping. We construct a new model of the HLR state by using the new experimental results.
