Query: Adiabatic connection from accurate wavefunction calculations   An extremely easy method for accurately calculating the adiabatic connection
of density functional theory is presented, and its accuracy tested on both
Hooke's atom and the He atom. The method is easy because calculations are
needed only for different values of parameters in the external potential, which
can be achieved with almost any electronic structure code.
