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…
Quasiparticle Interference and Strong Electron-Mode Coupling in the Quasi-One-Dimensional Bands of SrRuO
Zhenyu Wang, Daniel Walkup, Philip Derry +13
The single-layered ruthenate SrRuO has attracted a great deal of interest as a spin-triplet superconductor with an order parameter that may potentially break time reversal…
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…
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,…
