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…
Multiple quantum scar states and emergent slow-thermalization in the flat-band system
Yoshihito Kuno, Tomonari Mizoguchi, Yasuhiro Hatsugai
Quantum many-body scars (QMBS) appear in a flat-band model with interactions on the saw-tooth lattice. The flat-band model includes a compact support localized eigenstates, called…
Square-root topological phase with time-reversal and particle-hole symmetry
Tsuneya Yoshida, Tomonari Mizoguchi, Yoshihito Kuno +1
Square-root topological phases have been discussed mainly for systems with chiral symmetry. In this paper, we analyze the topology of the squared Hamiltonian for systems preserving…
Flat-band solutions in -dimensional decorated diamond and pyrochlore lattices: Reduction to molecular problem
Tomonari Mizoguchi, Hosho Katsura, Isao Maruyama +1
Flat-band models have been of particular interest from both fundamental aspects and realization in materials. Beyond the canonical examples such as Lieb lattices and line graphs, a…
Flat band, spin-1 Dirac cone, and Hofstadter diagram in the fermionic square kagome model
Tomonari Mizoguchi, Yoshihito Kuno, Yasuhiro Hatsugai
We study characteristic band structures of the fermions on a square kagome lattice, one of the two-dimensional lattices hosting a corner-sharing network of triangles. We show that…
Chiral edge modes in evolutionary game theory: a kagome network of rock-paper-scissors
Tsuneya Yoshida, Tomonari Mizoguchi, Yasuhiro Hatsugai
We theoretically demonstrate the realization of a chiral edge mode in a system beyond natural science. Specifically, we elucidate that a kagome network of rock-paper-scissors (K-RP…
