In Section III we use 2 independent random unitary operators to construct the arcsine ensemble obtained by superposition of two random maximally entangled states.
Generating random density matrices
The name ‘arcsine’ is due to the fact that the corresponding cumulative distribution is proportional to sin−1 px/2.

Moreover, the last integrand in (10) is somewhat different from the integrand in the integral (6) deﬁning C (neglecting the constant in front of the integral in (6)) in that in (6) we subtract J0 (ψ) from the arcsine.
The defect variance of random spherical harmonics
To account for this difference, we need to subtract J0 (ψ) from the arcsine in the integrand (10), thus obtaining a conditionally convergent integral.
The defect variance of random spherical harmonics
As it was explained in Section 2, to extract the asymptotics of Il , we will expand the arcsine on the RHS of (15) into the Taylor series around the origin; we will encounter only the odd moments of Pl (cos θ), due to the arcsine being an odd function.
The defect variance of random spherical harmonics
The advantage of the latter representation (18) over (15) is that the only powers that will appear in the Taylor expansion of the arcsine on the righthand side of (18) are of order ≥ 3, so that the moments of Pl (cos θ) are all identical to the corresponding moments of the scaling limit.
The defect variance of random spherical harmonics
Note that all the Taylor coeﬃcients ak of arcsine are positive (see (20)).
The defect variance of random spherical harmonics
Let us keep in mind that Mδ sitting on the unstable stationary point ψ = arcsin (cid:0) 1 is close to M , which is a circle, so that also the dynamics on Mδ can be reduced to the dynamics of a phase (see Fig. 1).
