Hybridization between surface flat bands and bulk bands in the topological nodal-line semimetal Sn $_{0.15}$ NbSe $_{1.75}$ probed via soft-point-contact spectroscopy

K. Kumarasinghe, C. Dissanayake, R. Munir +2

We report a detailed study of soft-point-contact spectroscopy of the superconducting topological nodal-line semimetal Sn $_{0.15}$ NbSe $_{1.75}$ with the superconducting transition t…

Enhancement of the superconducting transition temperature due to multiband effect in the topological nodal-line semimetal Pb $_{1 - x}$ Sn $_{x}$ TaSe $_{2}$

K. Kumarasinghe, A. Rahman, M. Tomlinson +4

We report a systematic study of the normal-state and superconducting properties of single crystal Pb $_{1 - x}$ Sn $_{x}$ TaSe $_{2}$ $(0 \leq x \leq 0.23)$ . Sn doping enhances the superco…

Formation of random singlets in the nanocrystalline quasi-one-dimensional spin-1/2 antiferromagnet Sr21Bi8Cu2(CO3)2O41

Yanbo Guo, Xinzhe Hu, Hasan Siddiquee +5

Induced by quenched disorder, random-singlet states occur in a variety of low-dimensional spin-1/2 antiferromagnets, some of them candidates for quantum spin liquids. Here we repor…
