Phonons reflect dynamic spin-state order in LaCoO
Alsu Ivashko, Taishun Manjo, Maximilian Kauth +17
We investigate lattice dynamics in LaCoO using inelastic neutron and x-ray scattering over $T = 2\mbox{-}650\,\mathrm{K}$, spanning the spin-state crossover at $T_{1} \approx 1…
Charge-density-wave quantum critical point under pressure in 2-TaSe
Yuliia Tymoshenko, Amir-Abbas Haghighirad, Rolf Heid +13
Suppressing of an ordered state that competes with superconductivity is one route to enhance superconducting transition temperatures. Whereas the effect of suppressing magnetic sta…
Giant electron-phonon coupling of the breathing plane oxygen phonons in the dynamic stripe phase of LaSrNiO
A. M. Merritt, A. D. Christianson, A. Banerjee +3
Doped antiferromagnets host a vast array of physical properties and learning how to control them is one of the biggest challenges of condensed matter physics. LaSrN…
Nematic correlation length in iron-based superconductors probed by inelastic x-ray scattering
A. M. Merritt, F. Weber, J. -P. Castellan +7
Nematicity is ubiquitous in electronic phases of high- superconductors, particularly in the Fe-based systems. We used inelastic x-ray scattering to extract the temperature-dep…
Nature and impact of stripe freezing in LaSrNiO
A. M. Merritt, D. Reznik, V. O. Garlea +2
LaSrNiO develops charge and spin stripe orders at temperatures of roughly 200 K, with modulation wave vectors that are temperature independent. Various probes…
Low-energy phonons in BiSrCaCuO and their possible interaction with electrons measured by inelastic neutron scattering
A. M. Merritt, J. -P. Castellan, T. Keller +4
Electron-phonon interaction in copper oxide superconductors is still enigmatic. Strong coupling for certain optic phonons is now well established experimentally, but theoretical un…
Absence of long wavelength nematic fluctuations in LiFeAs
Adrian Merritt, Jose Rodriguez-Rivera, Yu Li +4
We investigated long-wavelength nematic fluctuations in an Fe-based superconductor LiFeAs near q=(0.05,0,0) by measuring temperature-dependent renormalization of acoustic phonons t…
