Primary charge-4e superconductivity from doping a featureless Mott insulator

Zhi-Qiang Gao, Yan-Qi Wang, Ya-Hui Zhang +1

Superconductivity is usually understood as a phase in which charge- $2 e$ Cooper pairs are condensed. Charge- $4 e$ superconductivity has largely been discussed as a vestigial order at…

Incommensurate pair-density-wave correlations in two-leg ladder $t$ -- $J$ -- $J_{⊥}$ 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 $t$ - $J$ - $J_{⊥}$ ladder m…
