    Tomonaga–Luttinger liquid in the edge channels of a quantum spin Hall insulator

    Quantum spin Hall insulators are two-dimensional materials that host conducting helical electron states strictly confined to the one-dimensional boundaries.

    {Conformality loss and quantum criticality in topological Higgs electrodynamics in 2+1 dimensions

    The electromagnetic response of topological insulators and superconductors is governed by a modified set of Maxwell equations that derive from a topological Chern-Simons (CS) term in the effective Lagrangian with coupling constant kappa.

    {Internal screening and dielectric engineering in magic-angle twisted bilayer graphene}

    Magic-angle twisted bilayer graphene (MA-tBLG) has appeared as a tunable testing ground to investigate the conspiracy of electronic interactions, band structure, and lattice degrees of freedom to yield exotic quantum many-body ground states in a two-dimensional (2D) Dirac material framework.

    {Fermi-arc diversity on surface terminations of the magnetic Weyl semimetal Co3Sn2S2}

    Bulk-surface correspondence in Weyl semimetals ensures the formation of topological `` Fermi arc'' surface bands whose existence is guaranteed by bulk Weyl nodes.

    {Magnetic Weyl semimetal phase in a Kagome crystal}

    Weyl semimetals are crystalline solids that host emergent relativistic Weyl fermions and have characteristic surface Fermi-arcs in their electronic structure.

    Magnon interactions in the frustrated pyrochlore ferromagnet Yb2Ti2O7

    The frustrated rare-earth pyrochlore Yb2Ti2O7 is remarkable among magnetic materials: despite a ferromagnetically ordered ground state it exhibits a broad, nearly gapless, continuum of excitations.

    {Orthogonal metal in the Hubbard model with liberated slave spins}

    A two-dimensional Falicov-Kimball model, equivalent to the Hubbard model in an unconstrained slave-spin representation, is studied by quantum Monte Carlo simulations.
