Unconventional pairing and electronic dimerization instabilities in the doped Kitaev-Heisenberg model

Daniel D. Scherer, Michael M. Scherer, Giniyat Khaliullin +2

We study the quantum many-body instabilities of the $t-J_{\mathrm{K}}-J_{\mathrm{H}}$ Kitaev-Heisenberg Hamiltonian on the honeycomb lattice as a minimal model for a doped spin-…
