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…
Reply to arXiv:2103.10268 `Comment on "Crossover of Charge Fluctuations across the Strange Metal Phase Diagram'''
Ali Husain, Matteo Mitrano, Melinda S. Rak +8
We recently reported [1,2] measurements of the charge density fluctuations in the strange metal cuprate BiSrCaCuO using both reflection M-EE…
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…
Crossover of Charge Fluctuations across the Strange Metal Phase Diagram
A. A. Husain, M. Mitrano, M. S. Rak +6
A normal metal exhibits a valence plasmon, which is a sound wave in its conduction electron density. The mysterious strange metal is characterized by non-Boltzmann transport and vi…
Anomalous density fluctuations in a strange metal
M. Mitrano, A. A. Husain, S. Vig +9
A central mystery in high temperature superconductivity is the origin of the so-called "strange metal," i.e., the anomalous conductor from which superconductivity emerges at low te…
