Discovery of the topological surface state in a noncentrosymmetric superconductor BiPd
Madhab Neupane, Nasser Alidoust, Su-Yang Xu +9
Recently, noncentrosymmetric superconductor BiPd has attracted considerable research interest due to the possibility of being a topological superconductor. Here, we report a system…
Topological Nodal-Line Fermions in the Non-Centrosymmetric Superconductor Compound PbTaSe2
Guang Bian, Tay-Rong Chang, Raman Sankar +18
We report the identification of a Topological Nodal-Line Semimetal state in PbTaSe2.
Visualizing the mixed bonding properties of liquid boron with high resolution Compton scattering
J. T. Okada, P. H. -L. Sit, Y. Watanabe +11
Bonding characteristics of liquid boron at 2500K are studied by using high resolution Compton scattering. An excellent agreement is found between the measurements and the correspon…
Two distinct topological phases in the mixed valence compound YbB6 and its differences from SmB6
Tay-Rong Chang, Tanmoy Das, Peng-Jen Chen +6
We discuss the evolution of topological states and their orbital textures in the mixed valence compounds SmB6 and YbB6 within the framework of the generalized gradient approximatio…
Topological semimetals and topological insulators in rare earth monopnictides
Minggang Zeng, Chen Fang, Guoqing Chang +5
We use first principles calculations to study the electronic properties of rock salt rare earth monopnictides La (N, P, As, Sb, Bi). A new type of topological band crossing…
Unconventional transformation of spin Dirac phase across a topological quantum phase transition
Su-Yang Xu, Madhab Neupane, Ilya Belopolski +15
The topology of a topological material can be encoded in its surface states. These surface states can only be removed by a bulk topological quantum phase transition into a trivial…
