Ultracold atoms allow SU(3) Fermi-Hubbard model studies. Researchers found similar magnetic correlations and non-s-wave pairing in doped SU(3) triangular lattices compared to SU(2) square lattices.
Area of Science:
- Quantum simulation
- Condensed matter physics
- Ultracold atomic gases
Background:
- Ultracold alkaline-earth atoms and molecules enable experimental SU(N)-symmetric Fermi-Hubbard models.
- Theoretical understanding of these systems, especially at finite doping, is limited.
Purpose of the Study:
- Investigate the strong-coupling limit of the SU(3) Fermi-Hubbard model on a triangular lattice.
- Analyze correlations and doped hole structures across the full doping range.
Main Methods:
- Employed a three-flavor extension of Gutzwiller-projected hidden fermion determinant states (G-HFDS).
- Utilized a neural network-based variational ansatz.
- Analyzed two- and three-point spin-spin and spin-spin-hole correlations of SU(3) Cartan generators.
Main Results:
- Observed strikingly similar magnetic correlations to the SU(2) square lattice equivalent.
- Identified non-s-wave pairing symmetry.
- Found enhanced binding energies for doped holes.
Conclusions:
- Results provide a foundation for exploring doped SU(N) Mott insulators.
- Offers insights for theoretical advancements and quantum simulation experiments.
