Abstract

The axial anomaly in a quasi-one-dimensional (quasi-1D) chiral p-wave superfluid model, which has a epsilon_x p_x+i epsilon_y p_y-wave gap in 2D is studied. The anomaly causes an accumulation of the quasiparticle and a quantized chiral current density in an inhomogeneous magnetic field. These effects are related to the winding number of the gap. By varying the parameters epsilon_x and epsilon_y, the model could be applicable to Sr2RuO4 near the second superconducting transition point, some quasi-1D organic superconductors and the fractional quantum Hall state at nu = 5 / 2 Landau level filling factor.
