Retardation effects in the Holstein-Hubbard chain at half-filling
Ka-Ming Tam, S. -W. Tsai, D. K. Campbell +1
The ground state phase diagram of the half-filled one-dimensional Holstein-Hubbard model contains a charge-density-wave (CDW) phase, driven by the electron-phonon (e-ph) coupling,…

Phase Diagram of the Holstein-Hubbard Two-Leg Ladder
Ka-Ming Tam, S. -W. Tsai, D. K. Campbell +1
Using a functional renormalization group method, we obtain the phase diagram of the two-leg ladder system within the Holstein-Hubbard model, which includes both electron-electron a…
