Two coupled frustrated Haldane chains show an extended Ashkin-Teller quantum phase transition separating a plaquette phase from a uniform disordered phase, with connections to Haldane and dimerized phases via Gaussian and Ising transitions.
A dipole-conserving spin chain with Ising interactions stabilizes antiferromagnetic dipole order at the level of spin pairs and undergoes transitions to conventional antiferromagnetic or ferromagnetic order depending on interaction sign and strength.
Lattice model states for Laughlin, Moore-Read, and Z_k Read-Rezayi fractional quantum Hall series are constructed with idealized energy, entanglement, and modified clustering properties distinct from continuum versions.
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.
A quantum channel applied near the entanglement cut maps the reduced density matrix of trivial gSPT states to non-trivial ones, thereby predicting their boundary CFT entanglement spectra.
Long-range dipolar interactions on a breathed Kagome lattice stabilize a chiral spin liquid, identified via DMRG and proposed for adiabatic preparation and edge-mode detection.
