Flat bands near the Fermi level observed in noncentrosymmetric type-II Weyl semimetal TaRhTe4 by ARPES, not predicted by DFT calculations.
COO co-optimizes orbitals with TrimCI to absorb many-body correlations into the basis, cutting determinant count by orders of magnitude for iron-sulfur clusters versus localized bases or DMRG.
Twisted 1T-ZrS₂ and 1T-SnSe₂ host isolated topological moiré valence bands with quantum spin Hall and high spin Chern states that arise from inter-branch and inter-orbital coupling under approximate spin-U(1) symmetry.
Optimization of mode spread in multimode fibers yields self-organized concentric ring patterns that become irregular at high mode counts, analogous to maximally localized Wannier functions.
COGITO creates accurate tight-binding models from DFT that match MLWF accuracy while keeping the orbitals chemically interpretable and projected onto atomic centers.
Strong trigonal crystal field plus subdominant hoppings in MnV2O4 stabilize canted two-in/two-out magnetism intertwined with dipole-quadrupole orbital order.
