Kohn-Sham Hamiltonian from Effective Field Theory: Quasiparticle Band Narrowing from Frozen Core Dynamics
Kohn-Sham eigenvalues equal quasiparticle bands up to a frozen-core renormalization z_core derived from effective field theory, resolving the long-standing ARPES bandwidth discrepancy in metals.
