Relationship between two-particle topology and fractional Chern insulator
Nobuyuki Okuma, Tomonari Mizoguchi
Lattice generalizations of fractional quantum Hall (FQH) systems, called fractional Chern insulators (FCIs), have been extensively investigated in strongly correlated systems. Desp…
Unconventional gapless semiconductor in an extended martini lattice in covalent honeycomb materials
Tomonari Mizoguchi, Yanlin Gao, Mina Maruyama +2
We study characteristic electronic structures in an extended martini lattice model and propose its materialization in -electron networks constructed by designated chemisorption…
Molecular-orbital representation with random U(1) variables
Tomonari Mizoguchi, Yasuhiro Hatsugai
We propose random tight-binding models that host macroscopically degenerate zero energy modes and belong to the unitary class. Specifically, we employ the molecular-orbital represe…
Higher-Order Topological Insulator on a Martini Lattice and Its Square Root Descendant
Daiki Matsumoto, Tomonari Mizoguchi, Yasuhiro Hatsugai
Notion of square-root topological insulators have been recently generalized to higher-order topological insulators. In two-dimensional square-root higher-order topological insulato…
