Twisted homobilayer transition metal dichalcogenide (TMD) attracts an expanding experimental interest recently for exhibiting a variety of topological and magnetic states even at zero magnetic field. Most of the studies right now focus on hole filling nu_h < 1, while a rich phase diagram at higher hole filling calls for more investigation. We perform a thorough survey of possible interaction-driven phases at higher integer hole fillings. We first construct the continuum model from a first-principles calculation, and then perform a self-consistent Hartree-Fock study of the interacting ground states. We identify various valley polarized (VP) states at odd integer fillings and intervalley coherent (IVC) states at even integer fillings and discuss the energetics competition among them. We also discuss the origin and the experimental implications of the curious Chern insulator at nu_h = 2.

  1. A quantum geometric mechanism for chiral domain wall metastability: Application to twisted transition-metal dichalcogenides

    cond-mat.str-el 2026-08 conditional novelty 8.0 of 10

    Chiral domain walls in conjugate Chern bands bind a dipole density set by a geometric coefficient c_G, producing a metastable texture that explains long-lived excitations in twisted MoTe2.

  2. Exciton-Anyon Binding in Fractional Chern Insulators: Spectral Fingerprints

    cond-mat.str-el 2026-01 unverdicted novelty 7.0 of 10

    Exciton-quasihole bound states emerge in a tunable lattice model of fractional Chern insulators, appearing as isolated levels in the spectrum due to residual attraction from charge depletion.

  3. Induced Zeeman effect of moir\'e surface states in topological insulators

    cond-mat.mes-hall 2025-07 conditional novelty 6.0 of 10

    An orbital magnetic field induces an effective Zeeman term in moiré surface states, tilting the zeroth Landau level linearly with field strength.

  4. Diffusion Models for Future Networks and Communications: A Comprehensive Survey

    cs.LG 2025-08 unverdicted novelty 3.0 of 10

    The abstract promises a comprehensive survey of diffusion models for wireless communications, but the supplied full text is a garbled and unrelated manuscript on moiré materials.
