英文摘要: Commencing with the composite fermion ( CF) description of the nu = 5/ 2 fractional quantum Hall effect, we study the dynamics of the edge neutral Majorana fermions. We confirm that these neutral modes are chiral and show that a conventional p-wave pairing interaction between CFs does not contribute to the dynamics of the edge neutral fermions. We find an important bilinear coupling between the charged and neutral modes. We show that owing to this coupling, the dispersion of the neutral modes is linear and their velocities are proportional to the wavevector of the charged mode. This dynamic origin of the motion of the edge Majorana fermions has never been predicted before.
