Comment:

 breaks plot in this case:
 {{{
 sage: var('n,a')
 sage: hbar, m = 1,1
 sage: psi(x,t,n)=sqrt(2/a)*sin(n*pi*x/a)*e^(-i*n^2*pi^2*hbar*t/(2*m*a^2));
 sage: print psi
 sage: Psi(x,t)=1/sqrt(2)*psi(x,t,1)+1/sqrt(2)*psi(x,t,2);
 sage: print Psi
 sage: P(x,t,a) = Psi.conjugate()*Psi
 sage: print P.expand()
 sage: plot(P(x,1,1),x,0,1)
 }}}
