Measurement of the dynamic charge response of materials using low-energy, momentum-resolved electron energy-loss spectroscopy (M-EELS)
Sean Vig, Anshul Kogar, Matteo Mitrano +9
One of the most fundamental properties of an interacting electron system is its frequency- and wave-vector-dependent density response function, . The imaginary part,…
Surface collective modes in the topological insulators BiSe and BiSbTeSe
A. Kogar, S. Vig, A. Thaler +13
We used low-energy, momentum-resolved inelastic electron scattering to study surface collective modes of the three-dimensional topological insulators BiSe and BiSb$…
Structural contributions to the pressure-tuned charge-density-wave to superconductor transition in ZrTe3: Raman scattering studies
S. L. Gleason, Y. Gim, T. Byrum +8
Superconductivity evolves as functions of pressure or doping from charge-ordered phases in a variety of strongly correlated systems, suggesting that there may be universal characte…
A reexamination of the effective fine structure constant of graphene, as measured in graphite
Yu Gan, Gilberto de la Pena Munoz, Anshul Kogar +5
We present a refined and improved study of the influence of screening on the effective fine structure constant of graphene, , as measured in graphite using inelastic x-ray sca…
