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…
Quasi-periodic flat-band model constructed by molecular-orbital representation
Tomonari Mizoguchi, Yasuhiro Hatsugai
We construct a tight-binding model that hosts both a quasi-periodic nature and marcoscopically-dengenerate zero-energy modes. The model can be regarded as a counterpart of the Aubr…
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,…
Topological pump and its plateau transitions of -leg spin ladder
Kota Yamamoto, Yoshihito Kuno, Tomonari Mizoguchi +2
A topological pump on an leg spin ladder is discussed by introducing spatial clusterization whose adiabatic limit is a set of site staircase clusters. We…
