The second altermagnet candidate in organic conductors: $κ$ -(BEDT-TTF) $_{2}$ $m$ -HOOCC $_{6}$ H $_{4}$ SO $_{3}$

Kohei Tokura, Takato Masuta, Kazushi Aoyama +3

We have developed a novel BEDT-TTF-based organic conductor, $κ$ -(BEDT-TTF) $_{2} m$ -HOOCC $_{6}$ H $_{4}$ SO $_{3}$ ( $κ$ - $m$ -SBA), and propose it as a candidate for altermagnet. Tight-binding ba…

Observation of the crossover from quantum fluxoid to half-quantum fluxoid in a chiral superconducting device

Masashi Tokuda, Fumiya Matsumoto, Noriaki Maeda +16

Topological superconductors are one of the intriguing material groups from the viewpoint of not only condensed matter physics but also industrial application such as quantum comput…

RKKY interaction in the presence of a charge-density-wave order

Kazushi Aoyama

Effects of a charge-density-wave (CDW) order on the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction has been theoretically investigated. Assuming that the CDW with an incommensura…

Effects of frequency mixing on Shapiro-step formations in sliding charge-density-waves

Yu Funami, Kazushi Aoyama

A one-dimensional charge density wave (CDW) is driven to slide by a dc electric field, carrying an electric current. In an additional ac field with frequency $ω_{ex}$ , it…
