Majorana edge magnetization in the Kitaev honeycomb model
Tomonari Mizoguchi, Tohru Koma
We propose an approach to detect the peculiarity of Majorana fermions at the edges of Kitaev magnets. As is well known, a pair of Majorana edge modes is realized when a single comp…
Flat-band engineering in tight-binding models: Beyond the nearest-neighbor hopping
Tomonari Mizoguchi, Masafumi Udagawa
In typical flat-band models, defined as nearest-neighbor tight-binding models, flat bands are usually pinned to the special energies, such as top or bottom of dispersive bands, or…
Phase diagram of disordered higher-order topological insulator: A machine learning study
Hiromu Araki, Tomonari Mizoguchi, Yasuhiro Hatsugai
A higher-order topological insulator is a new concept of topological states of matter, which is characterized by the emergent boundary states whose dimensionality is lower by more…
Magnetic clustering, half-moons, and shadow pinch points as signals of a proximate Coulomb phase in frustrated Heisenberg magnets
Tomonari Mizoguchi, Ludovic D. C. Jaubert, Roderich Moessner +1
We study the formation of magnetic clusters in frustrated magnets in their cooperative paramagnetic regime. For this purpose, we consider the -- classical Heisenberg…
Dzyaloshinskii-Moriya Interaction between Multipolar Moments in Systems
Masashi Hosoi, Tomonari Mizoguchi, Taichi Hinokihara +2
We propose a new type of Dzyaloshinskii-Moriya (DM) interactions which act on high-rank multipolar moments such as quadrupolar and octupolar moments. Here we consider 5d1 systems w…
