Lattice DQMC simulations of mixed QED3 with flavor chemical potential identify a chiral flux phase featuring spontaneous emergent gauge flux, broken U(1)m symmetry, and relativistic Landau levels for Dirac fermions.
YbCu1.14Se2 exhibits random singlet physics driven by exchange disorder in its 2D triangular lattice rather than quantum spin liquid behavior.
