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…
Two-electron photoemission spectroscopy in Topological Superconductors
Ka Ho Wong, Ameya Patwardhan, Peter Abbamonte +2
We demonstrate that the photo-electron counting rate, , measured in two electron coincidence spectroscopy (2-ARPES) experiments, provides unprecedented insight into the…
Anomalous high-temperature THz nonlinearity in superconductors near the metal-insulator transition
Dipanjan Chaudhuri, David Barbalas, Ralph Romero +5
The interplay of strong disorder and superconductivity is a topic of long-term interest in condensed matter physics. Here we explore the nonlinear THz response of superconducting N…
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…
BCS -wave behavior in the THz electrodynamic response of electron-doped cuprate superconductors
Zhenisbek Tagay, Fahad Mahmood, Anaelle Legros +3
Although cuprate superconductors have been intensively studied for the past decades, there is no consensus regarding the microscopic origin of their superconductivity. In this work…
Observation of a marginal Fermi glass using THz 2D coherent spectroscopy
Fahad Mahmood, Dipanjan Chaudhuri, Sarang Gopalakrishnan +2
A longstanding open problem in condensed matter physics is whether or not a strongly disordered interacting insulator can be mapped to a system of effectively non-interacting local…
