Microwave Kerr/Faraday Resonance in Two-dimensional Chiral Superconductors
Taiki Matsushita, Jun'ichi Ieda, Yasufumi Araki +3
We investigate the polar Kerr and Faraday effects in two-dimensional multiband chiral superconductors. We show that the clapping modes--the relative phase and amplitude oscillation…
Intrinsic spin Nernst effect in spin-triplet superconductors
Taiki Matsushita, Youichi Yanase, Takeshi Mizushima +2
We theoretically investigate the intrinsic (impurity-independent) spin Nernst effect (SNE), a spin current generation perpendicular to temperature gradients, in spin-triplet superc…
Impurity bands, line-nodes, and anomalous thermal Hall effect in Weyl superconductors
Taiki Matsushita, Naoyuki Kimura, Takeshi Mizushima +2
We investigate the anomalous thermal Hall effect (ATHE) in Weyl superconductors realized by the (-wave and -wave) chiral superconducting order for the point group $D…
Topological piezoelectric effect and parity anomaly in nodal line semimetals
Taiki Matsushita, Satoshi Fujimoto, Andreas P. Schnyder
Lattice deformations act on the low-energy excitations of Dirac materials as effective axial vector fields. This allows to directly detect quantum anomalies of Dirac materials via…
Disorder-induced exceptional and hybrid rings in Weyl/Dirac semimetals
Taiki Matsushita, Yuki Nagai, Satoshi Fujimoto
Non-Hermiticity in Weyl Hamiltonian leads to the realization of Weyl exceptional rings and flat bands inside the Weyl exceptional rings. Recently, the platform of non-Hermitian phy…
Negative thermal magnetoresistivity as a signature of chiral anomaly in Weyl superconductors
Takuro Kobayashi, Taiki Matsushita, Takeshi Mizushima +2
We propose that chiral anomaly of Weyl superconductors gives rise to negative thermal magnetoresistivity induced by emergent magnetic fields, which are generated by vortex textures…
