Vertex-corrected perturbation theory for the electron-phonon problem with non-constant density of states
J. K. Freericks, V. Zlatic', Woonki Chung +1
A series of weak-coupling perturbation theories which include the lowest-order vertex corrections are applied to the attractive Holstein model in infinite dimensions. The approxima…

Charge-transfer metal-insulator transitions in the spin-one-half Falicov-Kimball model
Woonki Chung, J. K. Freericks
The spin-one-half Falicov-Kimball model is solved exactly on an infinite-coordination-number Bethe lattice in the thermodynamic limit. This model is a paradigm for a charge-transfe…
