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.
A structure-preserving low-rank factorization of 2RDMs achieves linear rank scaling with system size and ~99% compression while retaining chemical accuracy for correlated states.
HAML meta-learns a mapping from control inputs and device parameters to effective two-qubit Hamiltonian coefficients via simulation training, then adapts online with few measurements, recovering coefficients where Schrieffer-Wolff perturbation theory fails.
