Consistency between reflection M-EELS and optical spectroscopy measurements of the long-wavelength density response of BiSrCaCuO
Jin Chen, Xuefei Guo, Christian Boyd +11
The density fluctuation spectrum captures many fundamental properties of strange metals. Using momentum-resolved electron energy-loss spectroscopy (M-EELS), we recently showed that…
Anharmonic multiphonon origin of the valence plasmon in SrTi1-xNbxO3
Caitlin S. Kengle, Samantha I. Rubeck, Melinda Rak +10
Doped SrTi1-xNbxO3 exhibits superconductivity and a mid-infrared optical response reminiscent of copper-oxide superconductors. Strangely, its plasma frequency, omega_p, increases b…
Kramers-Weyl fermions in the chiral charge density wave material (TaSe)I
Soyeun Kim, Robert C. McKay, Nina Bielinski +11
The quasi-one-dimensional chiral charge density wave (CDW) material (TaSe)I has been recently predicted to host Kramers-Weyl (KW) fermions which should exist in the vicinit…
Observation of Pines' Demon in SrRuO
A. A. Husain, E. W. Huang, M. Mitrano +11
The characteristic excitation of a metal is its plasmon, which is a quantized collective oscillation of its electron density. In 1956, David Pines predicted that a distinct type of…
Signatures of exciton condensation in a transition metal dichalcogenide
Anshul Kogar, Melinda S. Rak, Sean Vig +9
Bose condensation has shaped our understanding of macroscopic quantum phenomena, having been realized in superconductors, atomic gases, and liquid helium. Excitons are bosons that…
