What is the Hamiltonian in the adiabatic connection?

I have resolved my problem. The source of my confusion was mistaking the integrand $E_{xc,\lambda}$ at specific values of $\lambda$ with $E_{xc}$ itself. Hybrid functionals can be motivated by linear ...

What is the Hamiltonian in the adiabatic connection?

Your $\lambda=0$ definition corresponds to the complete neglect of interelectronic interactions. There is nothing to prevent you from doing that in principle, but the resulting approximation you would ...
