Pair-density-wave correlations in the Kondo-Heisenberg model

Research output: Contribution to journalArticle


We show, using density-matrix renormalization-group calculations complemented by field-theoretic arguments, that the spin-gapped phase of the one dimensional Kondo-Heisenberg model exhibits quasi-long-range superconducting correlations only at a nonzero momentum. The local correlations in this phase resemble those of the pair-density-wave state which was recently proposed to describe the phenomenology of the striped ordered high-temperature superconductor La2-xBaxCuO4, in which the spin, charge, and superconducting orders are strongly intertwined.
