where N 1 is the normalization constant determined by the following equation<br />
∫<br />
4π<br />
rdr |u 0 (r)| 2 = 1. (3.9)<br />
Evaluation <strong>of</strong> the integral yields:<br />

In the opposite limit ∆ 2 0 > 2mµvF 2 , the solution <strong>of</strong> Eq. (3.7) is given by first<br />
order imaginary Bessel function:<br />
√<br />
χ(r) = N 2 I 1 (r ∆ 2 0/vF 2 − 2mµ). (3.12)<br />
The function I n (r) diverges when r → ∞.<br />
But the radial wave function u 0 (r)<br />
remains bounded as long as µ > 0. This is consistent with the fact that µ = 0<br />
separates topologically trivial phase (µ < 0) and non-Abelian phase (µ > 0) [19].<br />
We now give expressions for N 2 . Explicitly, it is given by<br />

rdr I 2 1(k 2 r)e −2r/ξ = 1, (3.13)<br />
where k 2 = √ ∆ 2 0/v 2 F − 2mµ. Since µ > 0, k 2ξ is always smaller than 1. We find N 2<br />
is given by<br />
