Correlated Zak insulator in organic antiferromagnets
Takahiro Misawa, Makoto Naka
Searching for topological insulators in solids is one of the main issues of modern condensed matter physics since robust gapless edge or surface states of the topological insulator…
Anomalous Hall effect in antiferromagnetic perovskites
Makoto Naka, Yukitoshi Motome, Hitoshi Seo
We theoretically study the anomalous Hall effect (AHE) in perovskites with antiferromagnetic (AFM) orderings. By studying the multiorbital Hubbard model for electrons in perovs…
Phonon renormalization effects accompanying the 6 K anomaly in the Quantum Spin Liquid Candidate -(BEDT-TTF)Cu(CN)
Masato Matsuura, Takahiko Sasaki, Makoto Naka +5
The low-temperature state of the quantum spin liquid candidate -(BEDT-TTF)Cu(CN) emerges via an anomaly at K. Although signatures of this anomaly…
Antiferromagnetic State in -type Molecular Conductors: Spin Splitting and Mott Gap
Hitoshi Seo, Makoto Naka
We numerically investigate the dynamical properties of -type molecular conductors in their antiferromagnetic Mott insulating state. By treating the extended Hubbard model on the…
Spin Seebeck Effect in Nonmagnetic Excitonic Insulators
Joji Nasu, Makoto Naka
We propose a mechanism of the spin Seebeck effect attributed to excitonic condensation in a nonmagnetic insulator. We analyze a half-filled two-orbital Hubbard model with a crystal…
Perovskite as a spin current generator
Makoto Naka, Yukitoshi Motome, Hitoshi Seo
We theoretically show that materials with perovskite-type crystal structures provide a platform for spin current generation, taking advantage of a mechanism requiring neither the s…
