Abstract
The triangular-lattice Fermi-Hubbard model has been extensively investigated in the literature due to its connection to chiral spin states and unconventional superconductivity. Previous simulations of the ground state of the doped system rely on quasi-one-dimensional lattices where true long-range order is forbidden. Here we simulate two-dimensional and quasi-one-dimensional triangular lattices using state-of-the-art Auxiliary-Field Quantum Monte Carlo. Upon doping a non-magnetic chiral spin state, we observe evidence of chiral superconductivity supported by long-range order in Cooper-pair correlation and a finite value of the chiral order parameter. With this aim, we first locate the transition from the metallic to the non-magnetic insulating phase and the onset of magnetic order. Our results pave the way towards a better understanding of strongly correlated lattice systems with magnetic frustration.
Featured image: Depiction of the triangular-lattice Fermi-Hubbard model. We display the lattice vectors $hat{e}_x = (a,0)$ and $hat{e}_y=(a/2,sqrt{3}a/2)$. The circle represents the formation of a doublon (doubly-occupied site) with energy cost $U$. We also show a hopping process with energy scale $-t$. Ellipses depict Cooper pairs in the singlet ($|srangle = (|uparrowdownarrowrangle – |downarrowuparrowrangle) /sqrt{2}$) or triplet ($|trangle = (|uparrowdownarrowrangle + |downarrowuparrowrangle) /sqrt{2}$) states formed on the $hat{e}_y$ and $hat{e}_x$ bounds of the triangular plaquettes.
