Stability of chiral spin liquid phase of the triangular lattice Hubbard model with hopping anisotropy

In our previous work (arXiv: 1808.00463), we showed using density matrix renormalization group (DMRG) simulations on infinite cylinders that the triangular lattice Hubbard model hosts a chiral spin liquid phase at intermediate interaction strength. However, the model we studied featured isotropic hopping, whereas real triangular lattice spin liquid candidate materials, such as κ-(BEDT-TTF)₂Cu₂(CN)₃, are not precisely isotropic. To better connect to experimental results in such spin liquid candidates, in this work we investigate the stability of the chiral spin liquid against anisotropy in the hopping and show that the phase survives, providing further support for the applicability of our findings to experiments.
