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,…
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$…
Temperature-resolution anomalies in the reconstruction of time dynamics from energy-loss experiments
Anshul Kogar, Sean Vig, Yu Gan +1
Inelastic scattering techniques provide a powerful approach to studying electron and nuclear dynamics, via reconstruction of a propagator that quantifies the time evolution of a sy…
