Emergence of ferroelectric topological insulator as verified by quantum Hall effect of surface states in (Sn,Pb,In)Te films
Ryutaro Yoshimi, Ryosuke Kurihara, Yoshihiro Okamura +9
Emergent phenomena arising from nontrivial band structures based on topology and symmetry have been attracting keen interest in contemporary condensed-matter physics. Materials suc…
Gapped nodal planes drive a large topological Nernst effect in a chiral lattice antiferromagnet
N. D. Khanh, S. Minami, M. Hirschmann +15
The electronic structure of compensated antiferromagnets (CAF) has drawn attention for its ability to create large responses, reminiscent of ferromagnets and suitable for data stor…
Terahertz lattice and charge dynamics in ferroelectric semiconductor SnPbTe
Y. Okamura, H. Handa, R. Yoshimi +5
The symmetry breaking induced by the ferroelectric transition often triggers the emergence of topological electronic states such as Weyl fermions in ferroelectric-like metals/semim…
Observation of magnetic excitations of skyrmion crystal in a helimagnetic insulator
Y. Onose, Y. Okamura, S. Seki +2
The skyrmion is a topologically stable spin texture, in which the spin direction wraps a sphere. The topological nature gives rise to emergent electromagnetic phenomena such as top…
