Query: Evidence of pair-density wave in doping Kitaev spin liquid on the
  honeycomb lattice   We study the effects of doping the Kitaev model on the honeycomb lattice
where the spins interact via the bond-directional interaction $J_K$, which is
known to have a quantum spin liquid as its exact ground state. The effect of
hole doping is studied within the $t$-$J_K$ model on a three-leg cylinder using
density-matrix renormalization group. Upon light doping, we find that the
ground state of the system has quasi-long-range charge-density-wave
correlations but short-range single-particle correlations. The dominant pairing
channel is the even-parity superconducting pair-pair correlations with
$d$-wave-like symmetry, which oscillate in sign as a function of separation
with a period equal to that of the spin-density wave and two times the
charge-density wave. Although these correlations fall rapidly (possibly
exponentially) at long distances, this is never-the-less the first example
where a pair-density wave is the strongest SC order on a bipartite lattice. Our
results may be relevant to ${\rm Na_2IrO_3}$ and $\alpha$-${\rm RuCl_3}$ upon
doping.
