Emergent Shastry-Sutherland network from square-kagome Heisenberg antiferromagnet with trimerization
Tomonari Mizoguchi
We study the square-kagome lattice Heisenberg antiferromagnet with the trimarized modulation. In the trimerized limit, each trimer hosts the four-fold degenearte ground sta…
Topological two-body interaction obstructing trivial ground states: an indicator of fractional Chern insulators
Nobuyuki Okuma, Tomonari Mizoguchi
The search for candidate materials for fractional Chern insulators (FCIs) has mainly focused on the topological and geometrical structures of single-particle Chern bands. However,…
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…
Construction of interacting flat-band models by molecular-orbital representation: Correlation functions, energy gap, and entanglement
Tomonari Mizoguchi, Yoshihito Kuno, Yasuhiro Hatsugai
We calculate correlation functions of exactly-solvable one-dimensional flat-band models by utilizing the "molecular-orbital" representation. The models considered in this paper hav…
Field-selective classical spin liquid and magnetization plateaus on kagome lattice
Kunio Tokushuku, Tomonari Mizoguchi, Masafumi Udagawa
We obtain a classical spin liquid (CSL) phase by applying a magnetic field in -- Ising model on a kagome lattice. As we proved in the previous study [Phys. Rev. Lett…
Oriented propagation of magnetization due to chiral edge modes in Kitaev-type models
Tomonari Mizoguchi, Tohru Koma, Yasuhito Yoshida
Detecting chiral edge modes in topological materials has been intensively pursued in experiments. However, the phenomena caused by the modes are not yet elucidated theoretically. W…
