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…
Spin caloritronics as a probe of nonunitary superconductors
Taiki Matsushita, Takeshi Mizushima, Yusuke Masaki +2
Superconducting spintronics explores the interplay between superconductivity and magnetism, sparking significant interest in nonunitary superconductors as a platform for novel magn…
Intrinsic Anomalous Thermal Hall Effect in the Unconventional Superconductor UTe2
Yukiyasu Moriya, Taiki Matsushita, Masahiko G. Yamada +2
We investigate the intrinsic anomalous thermal Hall effect as an effective probe of the order parameters of non-unitary pairing states of the putative spin-triplet superconductor U…
Anomalous acoustoelectric effect induced by clapping modes in chiral superconductors
Taiki Matsushita, Takeshi Mizushima, Ilya Vekhter +1
Clapping modes, which are relative amplitude and phase modes between two chiral components of Cooper pairs, are bosonic collective modes inherent to chiral superconductors. These m…
Spin-Nernst Effect in Time-Reversal-Invariant Topological Superconductors
Taiki Matsushita, Jiei Ando, Yusuke Masaki +3
We investigate the spin-Nernst effect in time-reversal invariant topological superconductors, and show that it provides a smoking-gun evidence for helical Cooper pairs. The spin-Ne…
Spectrum collapse of disordered Dirac Landau levels as topological non-Hermitian physics
Taiki Matsushita, Yuki Nagai, Satoshi Fujimoto
We investigate disorder effects on Landau levels in Dirac electron systems with the use of a non-Hermitian quasiparticle Hamiltonian formalism. This formalism reveals that spin-dep…
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…
Charge/Spin Supercurrent and the Fulde-Ferrell State Induced by Crystal Deformation in Weyl/Dirac Superconductors
Taiki Matsushita, Tianyu Liu, Takeshi Mizushima +1
It has been predicted that emergent chiral magnetic fields can be generated by crystal deformation in Weyl/Dirac metals and superconductors. The emergent fields give rise to chiral…
