(1 + sqrt(3))) Otherwise, it will only be simplified if assumptions allow: >>> w = w.subs(sqrt(3), sqrt(x + 3)) >>> sqrtdenest(sqrt((w**2).expand())) sqrt((sqrt(sqrt(sqrt(x + 3) + 1) + 1) + 1 + sqrt(2))**2) Notice that the argument of the sqrt is a ...
If relative momentum Q is much smaller compared to the average momentum of the pair K=(p1+p2)/2, then Eq. (5) can be expressed as: C2(Q,K)=1+|S~(Q,K)|2|S~(Q=0,K)|2. (6) Alternatively, with a simplified notation where the K-dependence is suppressed and a normalized ...
