Query: Doped Mott Insulators in the Triangular Lattice Hubbard Model   We investigate the evolution of the Mott insulators in the triangular lattice
Hubbard Model, as a function of hole doping $\delta$ in both the strong and
intermediate coupling limits. Using the advanced density matrix renormalization
group (DMRG) method, at light hole doping $\delta\lesssim 10\%$, we find a
significant difference between strong and intermediate couplings. Notably, at
intermediate coupling an unusual metallic state emerges, with short ranged spin
correlations but long ranged spin-chirality order. Moreover, no clear Fermi
surface or wave-vector is observed, this chiral metal also exhibits staggered
loop current, which breaks the translational symmetry. These features disappear
on increasing interaction strength or on further doping. At strong coupling,
the 120 degree magnetic order of the insulating magnet persists for light
doping, and produces hole pockets with a well defined Fermi surface. On further
doping, $\delta \approx 10\%\sim 20\%$ SDW order and coherent hole Fermi
pockets are found at both strong and intermediate couplings. At even higher
doping $\delta \gtrsim 20\%$, the SDW order is suppressed and the spin-singlet
Cooper pair correlations are simultaneously enhanced. We also briefly comment
on the strong particle-hole asymmetry of the model.
