In the X-Q model the Néel-VBS transition is strongly first-order for N>2 because the X term cannot generate enough U(1) fluctuations of the dimer pattern.

The Kitaev-J3 model hosts deconfined magnetic phases in which zigzag or antiferromagnetic order coexists with remnant Z2 topological structure inherited from the Kitaev spin liquid through vison-pair condensation.
Doping-induced in-gap states in 1D and quasi-1D Kitaev-Hubbard models mirror the spin excitation spectra, including Ising gaps, Jordan-Wigner branches, and Z2 vison gaps.
One fixed layered t-J-V parameter set describes acousticlike plasmon dispersions from RIXS across the full doping range of La2-xSrxCuO4.
In the non-Hermitian XY model the scaling of ground-state correlations and entanglement entropy remains identical to the Hermitian version because Z2 symmetry breaking produces the ferromagnetic phase while U(1) symmetry emergence plus real-energy degeneracy produces the Luttinger liquid phase with
Numerical quench dynamics in 1D N-flavor Gross-Neveu lattice fermions show order-parameter equilibration consistent with ETH in the thermodynamic limit and GGE description, while finite-momentum correlations equilibrate only with nonzero reservoir coupling γ.
Hole-doped spin multimer systems exhibit superconductivity signatures when mapped to the hardcore boson model in the strong-binding-energy limit, with pairing persisting in DMRG simulations of the double Kondo lattice.

SU($N$) Quantum Spin Model with Weak and Strong First-Order N\'eel to Valence-Bond Solid Transitions
In the X-Q model the Néel-VBS transition is strongly first-order for N>2 because the X term cannot generate enough U(1) fluctuations of the dimer pattern.

Evidence for Deconfined Magnetic Order in the Kitaev-$J_3$ Model
The Kitaev-J3 model hosts deconfined magnetic phases in which zigzag or antiferromagnetic order coexists with remnant Z2 topological structure inherited from the Kitaev spin liquid through vison-pair condensation.

Relationship between doping-induced in-gap states and spin excitations in Kitaev-Hubbard models
Doping-induced in-gap states in 1D and quasi-1D Kitaev-Hubbard models mirror the spin excitation spectra, including Ising gaps, Jordan-Wigner branches, and Z2 vison gaps.

Survival of Hermitian Criticality in the Non-Hermitian Framework
In the non-Hermitian XY model the scaling of ground-state correlations and entanglement entropy remains identical to the Hermitian version because Z2 symmetry breaking produces the ferromagnetic phase while U(1) symmetry emergence plus real-energy degeneracy produces the Luttinger liquid phase with

Post-quench relaxation dynamics of Gross-Neveu lattice fermions
Numerical quench dynamics in 1D N-flavor Gross-Neveu lattice fermions show order-parameter equilibration consistent with ETH in the thermodynamic limit and GGE description, while finite-momentum correlations equilibrate only with nonzero reservoir coupling γ.

Superconductivity in doped spin multimer systems
Hole-doped spin multimer systems exhibit superconductivity signatures when mapped to the hardcore boson model in the strong-binding-energy limit, with pairing persisting in DMRG simulations of the double Kondo lattice.
