摘要：

We analyze an effective theory for double-layer quantum Hall systems whose effective Hamiltonian consists of a kinetic energy term for the Goldstone mode and a tunneling term for electrons. This system corresponds to the quantum ferromagnet theory recently proposed. It is shown that Josephson phenomena occur except for the Meissner effect. A detailed physical picture of the commensurate-incommensurate phase transition in the magnetic order is described on the analogy of superconductor Josephson junction. Plasmon excitations are analyzed in each phase. © 1995 The American Physical Society.
