Single-orbital tight-binding model for chiral one-dimensional hybrid organic-inorganic lead halide perovskites

Yuya Ominato, Tetsuya Furukawa, Ayumi Ishii +1

The paper introduces a single-orbital tight-binding model that captures the low‑energy electronic band structure and spin splittings of the chiral one‑dimensional hybrid organic‑in…

Spin Peltier effect in graphene

Xin Theng Lee, Xin Hu, Yuya Ominato +3

In this work, we theoretically investigate the spin-Peltier effect in a heterostructure composed of graphene and a ferromagnetic insulator (FI). Using a microscopic formalism based…

Circular dichroism in second- and third-harmonic generation in chiral topological semimetal CoSi

Yuya Ominato, Masahito Mochizuki

We theoretically investigate circular dichroism (CD) in second- and third-harmonic generation (SHG and THG) in the chiral topological semimetal CoSi. We demonstrate that both SHG a…

Ferromagnetic resonance modulation in topological materials with bulk--boundary coexistence

Shun Muto, Yuya Ominato, Takeo Kato +2

We extend ferromagnetic resonance (FMR) modulation theory to describe systems in which bulk and boundary states of topological materials coexist, with both appearing at the same en…

Probing valley quantum oscillations via the spin Seebeck effect in transition metal dichalcogenide/ferromagnet hybrids

Xin Hu, Yuya Ominato, Mamoru Matsuo

We theoretically investigate spin-valley-locked tunneling transport in a transition-metal dichalcogenide/ferromagnetic-insulator heterostructure under a perpendicular magnetic fiel…

Quantum oscillations of valley current driven by microwave irradiation in transition-metal dichalcogenide/ferromagnet hybrids

Xin Hu, Yuya Ominato, Mamoru Matsuo

We theoretically study spin and valley transport in a transition-metal dichalcogenide(TMDC)/ferromagnet heterostructure under a perpendicular magnetic field. We find that microwave…
