Query: Finite temperature quantum embedding theories for correlated systems   The cost of the exact solution of the many-electron problem is believed to be
exponential in the number of degrees of freedom, necessitating approximations
that are controlled and accurate but numerically tractable. In this paper, we
show that one of these approximations, the self-energy embedding theory (SEET),
is derivable from a universal functional and therefore implicitly satisfies
conservation laws and thermodynamic consistency. We also show how other
approximations, such as the dynamical mean field theory (DMFT) and its
combinations with many-body perturbation theory, can be understood as a special
case of SEET and discuss how the additional freedom present in SEET can be used
to obtain systematic convergence of results.
