The Role of Quantum Metastability and the Perspective of Quantum Glassiness in Kitaev Fractional Spin Dynamics: An NMR Study
Wassilios Papawassiliou, Nicolas Lazaridis, Eunice Mumba Mpanga +8
The suppression of magnetic order and the detection of a half-quantized thermal Hall effect in α-RuCl3 under an external magnetic field have sparked significant debate, whether the…
Detection of Weyl Fermions and the Metal to Weyl-Semimetal phase transition in WTe via broadband High Resolution NMR
Wassilios Papawassiliou, José P. Carvalho, Hae Jin Kim +11
Weyl Fermions (WFs) in the type-II Weyl Semimetal (WSM) WTe are difficult to resolve experimentally because the Weyl bands disperse in an extremely narrow region of the (E-k) s…
Direct observation of Dirac states in Bi2Te3 nanoplatelets by 125Te NMR
Wassilios Papawassiliou, Aleksander Jaworski, Andrew J. Pell +12
Detection of the metallic Dirac electronic states on the surface of Topological Insulators (TIs) is a tribune for a small number of experimental techniques the most prominent of wh…
Exfoliation of layered Na-ion anode material Na2Ti3O7 for enhanced capacity and cyclability
Maria A. Tsiamtsouri, Phoebe K. Allan, Andrew J. Pell +6
We report the exfoliation of layered Na2Ti3O7, a promising anode material for Na-ion batteries, and restacking using HNO3 and NaOH to form H-Ti3O7 and Na(x)-Ti3O7 compositions, res…
