Tunable competing optical excitation pathways in the topological surface states of BiTe
Shin Yokoyama, Takahito Takeda, Nagi Suzuki +9
Understanding coherent optical responses of topological surface states (TSSs) requires disentangling excitation pathways from the electronic band structure. Here, using angle-resol…
Realization of a parity-violating antiferromagnetic state in LaMnSi
Takuma Iwata, K. Shiraishi, T. Aoyama +12
Spontaneous symmetry breaking underlies functional electronic phenomena in quantum materials. Breaking space-inversion () or time-reversal () symmetry can…
Observation of spin splitting in the surface electronic structure of antiferromagnet NdBi
Rikako Yamamoto, Takeru Motoyama, Takuma Iwata +11
Spin splitting in electronic band structures via antiferromagnetic orders is a new route to control spin-polarized carriers that is available for spintronics applications. Here, we…
Hedgehog-like spin texture in Sb-doped MnBiTe
Meng Zeng, Shu Mo, Ke Zhang +13
We employ spin- and angle-resolved photoemission spectroscopy and circular-dichroism ARPES to systematically investigate the spin texture of Sb-doped MnBiTe. Our results di…
