Observation of Flat Bands in Type-II Weyl Semimetal TaRhTe
Harry Rankin, Tyler J. Slade, Benjamin Schrunk +7
Flat bands have been theoretically predicted for decades but have only recently been realized in quantum materials such as magic-angle twisted bilayer graphene, kagome and Lieb lat…
Observation of unexpected band splitting and magnetically-induced band structure reconstruction in TbTiBi
Yevhen Kushnirenko, Lin-Lin Wang, Xiaoyi Su +5
The magnetic Kagome materials are a promising platform to study the interplay between magnetism, topology, and correlated electronic phenomena. Among these materials, the RTi3Bi4 f…
Band structure and charge ordering of Dirac semimetal EuAl at low temperatures
Andrew Eaton, Brinda Kuthanazhi, Paul C. Canfield +6
EuAl is proposed to host a topological Hall state. This material also undergoes four consecutive antiferromagnetic (AFM) transitions upon cooling below TN1 = 15.4 K in the pres…
Unexpected changes in the band structure within AFM1 state of CeBi
Yevhen Kushnirenko, Brinda Kuthanazhi, Benjamin Schrunk +7
We perform angle-resolved photoemission spectroscopy (ARPES) measurements in conjunction with density functional theory (DFT) calculations to investigate the evolution of the elect…
Long-range magnetic order induced surface state in GdBi and DyBi
Yevhen Kushnirenko, Lin-Lin Wang, Zhuoqi Li +6
The recent discovery of unconventional surface-state pairs, which give rise to Fermi arcs and spin textures, in antiferromagnetically ordered rare-earth monopnictides attracted the…
