Phonon dispersion and low energy anomaly in CaC
Matteo D'Astuto, Matteo Calandra, N. Bendiab +10
We report measurements of phonon dispersion in CaC using inelastic X-ray and neutron scattering. We find good overall agreement, particularly in the 50 meV energy region, betwe…
Strong phonon softening without Fermi surface nesting
D. Lamago, M. Hoesch, M. Krisch +4
Interactions with electronic excitations can soften and/or broaden phonons. They are greatly amplified at wavevectors Q+- that connect parallel (nested) sheets of the Fermi surface…
Splitting in the Fermi surface of ZrTe_3: a surface charge density wave system
Moritz Hoesch, Xiaoyu Cui, Kenya Shimada +3
The electronic band structure and Fermi surface of ZrTe_3 was precisely determined by linearly polarized angle-resolved photoelectron spectroscopy. Several bands and a large part o…
Giant Kohn anomaly and the phase transition in charge density wave ZrTe_3
Moritz Hoesch, Alexey Bosak, Dmitry Chernyshov +2
A strong Kohn anomaly in ZrTe_3 is identified in the mostly transverse acoustic phonon branch along the modulation vector q_P with polarization along the a* direction. This soft mo…
