摘要：
The orbital motion of pancake vortices takes place as a result of momentum exchange with electromagnetic waves. The coherent wave for vortex motion is obtained from the Lorentz-covariant wave equation for vortices. When the static magnetic field is tilted from the c axis, the vortex orbit becomes elliptical due to an interlayer electromagnetic interaction or gauge current. The gauge current also produces a coupling between the vortex cyclotron motion and transverse Josephson plasma, which was experimentally observed. The cyclotron mass of superfluid electrons and the frequency of a transverse Josephson plasma were obtained in Bi2Sr2CaCu2O8+delta.
