Dynamic properties in the bilayer quantum Hall ferromagnet

Research output: Contribution to journalArticlepeer-review


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