Real-Space Visualization of Frequency-Dependent Anisotropy of Atomic Vibrations
Xingxu Yan, Paul M. Zeiger, Yifeng Huang +11
The underlying dielectric properties of materials, intertwined with intriguing phenomena such as topological polariton modes and anisotropic thermal conductivities, stem from the a…
Lessons from the harmonic oscillator -- a reconciliation of the Frequency-Resolved Frozen Phonon Multislice Method with other theoretical approaches
Paul M. Zeiger, Juri Barthel, Leslie J. Allen +1
We compare the Frequency-Resolved Frozen Phonon Multislice (FRFPMS) method, introduced in Phys. Rev. Lett. 124, 025501 (2020), with other theoretical approaches used to account for…
Control of the phonon band gap with isotopes in hexagonal boron nitride
Paul Zeiger, Jordan Hachtel, Dominik Legut +5
The isotopic mass of constituent elements of materials has a well-known effect on the energy of vibrational modes. By means of monochromated scanning transmission electron microsco…
Unveiling the impact of temperature on magnon diffuse scattering detection in the transmission electron microscope
José Ángel Castellanos-Reyes, Paul Zeiger, Anders Bergman +4
Magnon diffuse scattering (MDS) signals could be studied with high spatial resolution in scanning transmission electron microscopy (STEM), thanks to recent technological progress i…
