Quantum oscillations and anisotropic magnetoresistance in the quasi-two-dimensional Dirac nodal line superconductor
Yuxiang Gao, Kevin Allen, Rose Albu Mustaf +8
Recent interest in quantum materials has focused on systems exhibiting both superconductivity and non-trivial band topology as material candidates to realize topological or unconve…
Fermi surface and Berry phase analysis for Dirac nodal line semimetals: cautionary tale to SrGa and BaGa
Yuxiang Gao, Yichen Zhang, Shiming Lei +8
A Berry phase of odd multiples of inferred from quantum oscillations (QOs) has often been treated as evidence for nontrivial reciprocal space topology. However, disentangling t…
Aspheric lens design proposal for near-perfect mode-matching of a broadband quantum dot micropillar to a single-mode fibre
Yichen Zhang, David Dlaka, James McDougall +5
Quantum dots in micropillars are one of the most promising options for a bright, deterministic single photon source. While highly efficient devices (>95%) have been designed, there…
Kramers nodal lines in intercalated TaS superconductors
Yichen Zhang, Yuxiang Gao, Aki Pulkkinen +24
Kramers degeneracy is one fundamental embodiment of the quantum mechanical nature of particles with half-integer spin under time reversal symmetry. Under the chiral and noncentrosy…
Topological Surface State Evolution in BiSe via Surface Etching
Ziqin Yue, Jianwei Huang, Ruohan Wang +10
Topological insulators are materials with an insulating bulk interior while maintaining gapless boundary states against back scattering. BiSe is a prototypical topological…
