The Role of Quantum Metastability and the Perspective of Quantum Glassiness in Kitaev Fractional Spin Dynamics: An NMR Study

Autor: Papawassiliou, Wassilios, Lazaridis, Nicolas, Mpanga, Eunice Mumba, Koppe, Jonas, Panopoulos, Nikolaos, Karagianni, Marina, Gkoura, Lydia, Berthelot, Romain, Fardis, Michael, Pell, Andrew J., Papavassiliou, Georgios

The suppression of magnetic order and the detection of a half-quantized thermal Hall effect in {\alpha}-RuCl3 under an external magnetic field have sparked significant debate, whether these phenomena point to spin fractionalization, as posited by the

Detection of Weyl Fermions and the Metal to Weyl-Semimetal phase transition in WTe$_2$ via broadband High Resolution NMR

Autor: Papawassiliou, Wassilios, Carvalho, José P., Kim, Hae Jin, Kim, Chang-Yeon, Yoo, Seung Jo, Lee, Jin Bae, Alhassan, Saeed, Orfanidis, Savvas, Psycharis, Vassilios, Karagianni, Marina, Fardis, Michael, Panopoulos, Nikolaos, Papavassiliou, Georgios, Pell, Andrew J.

Weyl Fermions (WFs) in the type-II Weyl Semimetal (WSM) WTe$_2$ are difficult to resolve experimentally because the Weyl bands disperse in an extremely narrow region of the (E-k) space. Here, by using DFT-assisted high-resolution $^{125}$Te solid-sta

Direct observation of Dirac states in Bi2Te3 nanoplatelets by 125Te NMR

Autor: Papawassiliou, Wassilios, Jaworski, Aleksander, Pell, Andrew J., Jang, Jae Hyuck, Kim, Yeonho, Lee, Sang-Chul, Kim, Hae Jin, Alwahedi, Yasser, Alhassan, Saeed, Subrati, Ahmed, Fardis, Michael, Karagianni, Marina, Panopoulos, Nikolaos, Dolinsek, Janez, Papavassiliou, Georgios

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 which is Angle Resolved Photoemission Spectroscopy. However, there is no

Exfoliation of layered Na-ion anode material Na2Ti3O7 for enhanced capacity and cyclability

Autor: Tsiamtsouri, Maria A., Allan, Phoebe K., Pell, Andrew J., Stratford, Joshua M., Kim, Gunwoo, Kerber, Rachel N., Magusin, Pieter M., Jefferson, David A., Grey, Clare P.

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, respectively. The materials were characterised by a range of techniques (
