Numerical simulations of the dynamical dimer structure factor on the triangular Heisenberg model provide support for a gapless U(1) Dirac quantum spin liquid with gapless singlet monopole excitations at X = K/2 momenta.
Charge-pumping simulation extracts Chern numbers and identifies anomalous composite Fermi liquids from neural network wavefunctions in fractional Chern insulators.
Nematic Bond Theory is used to map finite-temperature phases and correlation lengths of the triangular-lattice Heisenberg model with up to third-neighbor exchanges, identifying spiral spin liquids along the J3 = J2/2 line.
Lattice DQMC simulations of mixed QED3 with flavor chemical potential identify a chiral flux phase featuring spontaneous emergent gauge flux, broken U(1)m symmetry, and relativistic Landau levels for Dirac fermions.
Infinite PEPS simulations find a direct Néel-to-QSL transition at J2/J1 ≈ 0.08 in the triangular J1-J2 model and indicate the QSL is gapless, consistent with a U(1) Dirac spin liquid.
YbCu1.14Se2 exhibits random singlet physics driven by exchange disorder in its 2D triangular lattice rather than quantum spin liquid behavior.
Integrated theory-numerics-experiment collaboration has already clarified key quantum-magnet models and materials, and is required to resolve remaining spin-liquid candidates.
The notes argue that the FL* state — small pockets plus a quantized spin-liquid anomaly — resolves the ADMR pocket and v_F >> v_Delta problems that defeated holon-metal and plain fermionic-parton theories of the cuprates.
