Higher-order topological superconductor phases in a multilayer system
Ryota Nakai, Kentaro Nomura
Higher-order topological phases are gapped phases of matter that host gapless corner or hinge modes. For the case of superconductors, corner or hinge modes are gapless Majorana mod…
Effective model analysis of intrinsic spin Hall effect with magnetism in stacked-kagome Weyl semimetal Co3Sn2S2
Akihiro Ozawa, Koji Kobayashi, Kentaro Nomura
We theoretically study the spin Hall effect in a simple tight-binding model of stacked-kagome Weyl semimetal Co3Sn2S2 with ferromagnetic ordering. We focus on the two types of the…
Effective Tight-Binding Model of Compensated Ferrimagnetic Weyl Semimetal with Spontaneous Orbital Magnetization
Tomonari Meguro, Akihiro Ozawa, Koji Kobayashi +1
The effective tight-binding model with compensated ferrimagnetic inverse-Heusler lattice TiMnAl, candidate material of magnetic Weyl semimetal, is proposed. The energy spectr…
Enhancement of Spin-Charge Conversion Efficiency for CoSnS across Transition from Paramagnetic to Ferromagnetic Phase
Takeshi Seki, Yong-Chang Lau, Junya Ikeda +5
CoSnS (CSS) is one of the shandite compounds and becomes a magnetic Weyl semimetal candidate below the ferromagnetic phase transition temperature ($\textit{T}_\te…
Andreev-like Reflection in the Pfaffian Fractional Quantum Hall Effect
Ryoi Ohashi, Ryota Nakai, Takehito Yokoyama +2
We studied the tunnel transport between the edge of a Pfaffian fractional quantum Hall state and that of an integer quantum Hall state. Based on the duality argument between the st…
Intercorrelated anomalous Hall and spin Hall effect in kagome-lattice CoSnS-based shandite films
Yong-Chang Lau, Junya Ikeda, Kohei Fujiwara +5
Magnetic Weyl semimetals (mWSMs) are characterized by linearly dispersive bands with chiral Weyl node pairs associated with broken time reversal symmetry. One of the hallmarks of m…
