Incommensurate pair-density-wave correlations in two-leg ladder $t$--$J$--$J_{\perp }$ model

Hanbit Oh, Julian May-Mann, Ya-Hui Zhang

We report the discovery of a generalized Luther-Emery liquid phase characterized by incommensurate pair-density-wave (iC-PDW) correlations in the two-leg $t$-$J$-$J_{\perp }$ ladder m…
