Tensor networks demonstrate DQCP stability in the 1D spin-phonon model only for high phonon frequencies, with a first-order transition below a critical value whose endpoint belongs to the four-state Potts universality class.
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.
Broad multi-spinon continua emerge in the high-energy spectra of ordered Kitaev magnets, offering a mechanism for spectral broadening distinct from conventional magnon decay.
Spin-3/2 impurity quadrupole moments in a Kitaev spin liquid jump discontinuously at flux-sector transitions and can therefore identify the surrounding emergent-flux sector.
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.
