• Strong Coupling Limit of the Holstein-Hubbard Model. Physical review letters Han, Z., Kivelson, S. A., Yao, H. 2020; 125 (16): 167001

  Abstract

  We analyze the quantum phase diagram of the Holstein-Hubbard model using an asymptotically exact strong coupling expansion. We find all sorts of interesting phases including a pair-density wave, a charge 4e (and even a charge 6e) superconductor, regimes of phase separation, and a variety of distinct charge-density-wave, spin-density-wave, and superconducting regimes. We chart the crossovers that occur as a function of the degree of retardation, i.e., the ratio of characteristic phonon frequency to the strength of interactions.
