Abstract

The spectral functions of pseudospin response functions in the bilayer quantum Hall system at ν = 1 are investigated numerically, where the pseudospin describes the layer degrdes of freedom. In the pseudospin ferromagnetic phase, the lowest-lying excitation branch is closely connected with the ground state through the fluctuations of pseudospin Sy and Sz, and this pseudospin-wave excitation branch plays a significant role in the tunneling-current properties in the system.
