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…
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…
Sharp optical phonon softening close to optimal doping in LaBaCuO
Matteo D'Astuto, Guy Dhalenne, Jeff Graf +6
We report a direct observation of a sharp Kohn-like anomaly in the doubly degenerate copper-oxygen bond-stretching phonon mode occurring at in La$_…
Momentum-resolved charge excitations in high-Tc cuprates studied by resonant inelastic x-ray scattering
K. Ishii, M. Hoesch, T. Inami +14
We report a Cu K-edge resonant inelastic x-ray scattering (RIXS) study of high-Tc cuprates. Momentum-resolved charge excitations in the CuO2 plane are examined from parent Mott ins…
Phonon Softening in Superconducting Diamond
M. Hoesch, T. Fukuda, T. Takenouchi +7
We observe strong softening of optical phonon modes in superconducting (Tc = 4.2 K) boron doped diamond near the Brillouin zone center using inelastic x-ray scattering from a CVD-g…
