Amplitude of jump motion signatures in classical vibration-jump dynamic
Peter S. M. Townsend, John Ellis
The classical Langevin dynamics of a particle in a periodic potential energy landscape are studied via the intermediate scattering function (ISF). By construction, the particle per…
Motion of water monomers reveals a kinetic barrier to ice nucleation on graphene
Anton Tamtögl, Emanuel Bahn, Marco Sacchi +7
The interfacial behaviour of water remains a central question to fields as diverse as protein folding, friction and ice formation[1,2]. While the structural and dynamical propertie…
Nanoscale Surface Dynamics of BiTe(111): Observation of a Prominent Surface Acoustic Wave and the Role of van der Waals Interactions
Anton Tamtögl, Davide Campi, Martin Bremholm +8
We present a combined experimental and theoretical study of the surface vibrational modes of the topological insulator BiTe. Using high-resolution helium-3 spin-echo spectr…
A Helium-Surface Interaction Potential of BiTe(111) from Ultrahigh-Resolution Spin-Echo Measurements
Anton Tamtögl, Michael Pusterhofer, Martin Bremholm +7
We have determined an atom-surface interaction potential for the HeBiTe(111) system by analysing ultrahigh resolution measurements of selective adsorption resonances. Th…
Polarisation in Spin-Echo Experiments: Multi-point and Lock-in Measurements
Anton Tamtögl, Benjamin Davey, David J. Ward +3
Spin-echo instruments are typically used to measure diffusive processes and the dynamics and motion in samples on ps and ns timescales. A key aspect of the spin-echo technique is t…
