    Magic-angle helical trilayer graphene by Devakul, Trithep, Ledwith, Patrick J., Xia, Li-Qiao, Uri, Aviram, de la Barrera, Sergio C., Jarillo-Herrero, Pablo, Fu, Liang

    Published 2024
    “…While nominally forming a supermoiré (or moiré-of-moiré) structure, we show that HTG locally relaxes into large regions of a periodic single-moiré structure realizing flat topological bands carrying nontrivial valley Chern number. These bands feature near-ideal quantum geometry and are isolated from remote bands by a very large energy gap, making HTG a promising platform for experimental realization of correlated topological states such as integer and fractional quantum anomalous Hall states.…”

    Sections and Unirulings of Families over ℙ1 by Pieloch, Alex

    Published 2024
    “…We reach the same conclusions, but with genus zero multisections instead of sections, if π has at most two singular fibres, and the first Chern class of X is supported in a single fibre of π. …”

    Non-Hermitian extension of the Haldane model induced by non-reciprocal hopping by Law, Yi Khing

    Published 2023
    “…The degeneracies in the non-Hermitian framework are categorized, followed by the Chern number topological phase transi- tions. In the presence of non-Hermiticity however, there is a failure of the correspon- dence between the bulk and the boundary which is attributed to the non-Hermitian skin effect. …”

    Acoustic valley edge states in a graphene-like resonator system by Yang, Yahui, Yang, Zhaoju, Zhang, Baile

    Published 2019
    “…Similar to a gapped graphene, gapless topological valley edge states can be found at a zigzag domain wall separating different domains with opposite valley Chern numbers, while an armchair domain wall hosts no gapless edge states. …”

    Non-invertible Condensation, Duality, and Triality Defects in 3+1 Dimensions by Choi, Yichul, Córdova, Clay, Hsin, Po-Shen, Lam, Ho T., Shao, Shu-Heng

    Published 2023
    “…Interestingly, the fusion coefficients are generally not numbers, but 2+1d TQFTs, such as invertible SPT phases, $${\mathbb {Z}}_N$$ Z N gauge theories, and $$U(1)_N$$ U ( 1 ) N Chern-Simons theories. The associativity of these algebras over TQFT coefficients relies on nontrivial facts about 2+1d TQFTs. …”
