Abstract Magnetic topological insulators exhibit unique electronic states due to the interplay between the electronic topology and the spin structure. The antiferromagnetic metal EuIn2As2 is a prominent candidate material in which exotic topological

Abstract Complexity of quantum phases of matter is often understood theoretically by using gauge structures, as is recognized by the $${{\mathbb{Z}}}_{2}$$ Z 2 and U(1) gauge theory description of spin liquids in frustrated magnets. Anomalous Hall ef

By using the joined or welded materials of dissimilar metals, the characteristics and performance of products and parts can be improved. The combination of copper and aluminum is difficult to weld. In this study, the impact joining of copper C1100 an

Abstract A finite residual linear term in the thermal conductivity at zero temperature in insulating magnets indicates the presence of gapless excitations of itinerant quasiparticles, which has been observed in some candidate materials of quantum spi

Abstract We perform magnetic susceptibility and magnetic torque measurements on the organic κ-(BEDT-TTF)2Hg(SCN)2Br, which is recently suggested to host an exotic quantum dipole-liquid in its low-temperature insulating phase. Below the metal-insulat

Topological transport of fermions is governed by the Chern numbers of the energy bands lying below the Fermi energy. For bosons, e.g., phonons and magnons in a crystal, topological transport is dominated by the Chern number of the lowest energy band

Joining of pure copper C1100 and aluminum alloy A6061-T6 plates of 5 mm thickness was investigated. The method was developed by one of the authors, in which the newly created surfaces of a pair of plates obtained by high-speed shear were immediately

We investigate the thermal-transport properties of the kagome antiferromagnet Cd-kapellasite (Cd-K). We find that a field-suppression effect on the longitudinal thermal conductivity κ_{xx} sets in below approximately 25 K. This field-suppression eff
