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…
The Peculiar Size and Temperature Dependence of Water Diffusion in Carbon Nanotubes studied with 2D NMR Diffusion-Relaxation D-T2eff Spectroscopy
L. Gkoura, G. Diamantopoulos, M. Fardis +8
It is well known that water inside hydrophobic nano-channels diffuses faster than bulk water. Recent theoretical studies have shown that this enhancement depends on the size of the…
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…
Ultrafast stratified diffusion of water inside carbon nanotubes. Direct experimental evidence with 2D (D-T2) NMR spectroscopy
J. Hassan, G. Diamantopoulos, L. Gkoura +10
Water, when confined at the nanoscale acquires extraordinary transport properties. And yet there is no direct experimental evidence of these properties at nanoscale resolution. Her…
Ultrafast control of nuclear spins using only microwave pulses: towards switchable solid-state quantum gates
George Mitrikas, Yiannis Sanakis, Georgios Papavassiliou
We demonstrate the control of the alpha-proton nuclear spin, I=1/2, coupled to the stable radical CH(COOH)2, S=1/2, in a gamma-irradiated malonic acid single crystal using only mic…
