On the 2-loop part of the Johnson cokernel
Yusuke Kuno, Masatoshi Sato
We study stable Sp-decompositions of the cokernel of the Johnson homomorphism. Continuing the work of Conant in 2016, which identified the 1-loop part of the Johnson cokernel as th…
Topological Reality Switch: Towards Bulk-Boundary Selective Lasing
Sayed Ali Akbar Ghorashi, Masatoshi Sato
The emergence of complex spectra in non-Hermitian systems causes dramatic changes even under weak perturbations, significantly hindering their precise control for study and integra…
Intrinsic spin Nernst effect in topological Dirac and magnetic Weyl semimetals
Taiki Matsushita, Akihiro Ozawa, Yasufumi Araki +2
We investigate the intrinsic spin Nernst effect (SNE), a transverse spin current induced by temperature gradients, in topological Dirac semimetals (TDSMs) and magnetic Weyl semimet…
Electromagnetic response of spinful Majorana fermions
Shingo Kobayashi, Masatoshi Sato
A remarkable feature of topological superconductors is the emergence of Majorana fermions in electron systems. Whereas the emergent Majorana fermions share the self-anti-particle p…
Phonon and Magnetic Excitations in Superconducting CaPtAs(FePtAs)
K. Ikeuchi, Y. Kobayashi, K. Suzuki +7
Inelastic neutron scattering studies have been carried out on selected phonons and magnetic excitations of a crystal of superconducting (SC) CaPtAs(FePtA…
Impurity Effects on the Superconducting Transition Temperature of NazCoO2.yH2O
M. Yokoi, H. Watanabe, Y. Mori +3
Superconducting transition temperature Tc of NazCo1-xMxO2.yH2O has been studied for M=Ir and Ga, which can substitute for Co. It has been found that Tc is suppressed by the M-atom…
