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…
Termination-Dependent Surface States and Magnetic Fingerprints of Chiral Helimagnet Cr1/3TaS2
Bo Liang, Xue Li, Congcong Le +36
Chiral helimagnets based on intercalated transition-metal dichalcogenides, characterized by nano-scale spin ordering, provide a powerful route to engineer chiral spin textures (e.g…
Unusual Dual Flat Bands and two-dimensional Dirac-node Arc State in Kagome Metal Ni3In2S2
Bo Liang, Yichen Liu, Jie Pang +36
Kagome materials are at the frontier of condensed matter physics. An ideal kagome lattice features only one geometrically frustrated flat band spanning the entire momentum space an…
Non-altermagnetic spin texture in MnTe
Meng Zeng, Pengfei Liu, Ming-Yuan Zhu +19
Recently, altermagnets have emerged as promising candidates in spintronics, uniquely combining large spin-polarized electronic states with zero net magnetization. A prominent examp…
Versatile multi-q antiferromagnetic charge order in correlated vdW metals

Crystal-symmetry-paired spin-valley locking in a layered room-temperature antiferromagnet
Fayuan Zhang, Xingkai Cheng, Zhouyi Yin +19
Recent theoretical efforts predicted a type of unconventional antiferromagnet characterized by the crystal symmetry C (rotation or mirror), which connects antiferromagnetic sublatt…
Photoelectron spin-polarization-control in the topological insulator Bi2Se3
Z. -H. Zhu, C. N. Veenstra, S. Zhdanovich +9
We study the manipulation of the photoelectron spin-polarization in BiSe by spin- and angle-resolved photoemission spectroscopy. General rules are established that enable c…
