Relaxation timescales and electron-phonon coupling in optically-pumped YBaCuO revealed by time-resolved Raman scattering
N. Pellatz, S. Roy, J-W. Lee +6
Time resolved measurements provide a new way to disentangle complex interactions in quantum materials due to their different timescales. We used pump-probe Raman scattering to inve…
Catalogue of phonon modes in several cuprate high-temperature superconductors from density functional theory
N. J. Jabusch, P. Dayal, A. F. Kemper
Cuprates are promising candidates for study in developing higher temperature superconductors. A thorough understanding of a material's phonon modes enables further investigation of…
Theory of time-resolved optical conductivity of superconductors:comparing two methods for its evaluation
John P. Revelle, Ankit Kumar, Alexander F. Kemper
Time-resolved optical conductivity is an oft-used tool to interrogate quantum materials driven out of equilibrium. Theoretically calculating this observable is a complex topic with…
Amplitude mode oscillations in pump-probe photoemission spectra from a d-wave superconductor
B. Nosarzewski, B. Moritz, J. K. Freericks +2
Recent developments in the techniques of ultrafast pump-probe photoemission have made possible the search for collective modes in strongly correlated systems out of equilibrium. In…
Review of the theoretical description of time-resolved angle-resolved photoemission spectroscopy in electron-phonon mediated superconductors
A. F. Kemper, M. A. Sentef, B. Moritz +2
We review recent work on the theory for pump/probe photoemission spectroscopy of electron-phonon mediated superconductors in both the normal and the superconducting states. We desc…
Theory of light-enhanced phonon-mediated superconductivity
M. A. Sentef, A. F. Kemper, A. Georges +1
We investigate the dynamics of a phonon-mediated superconductor driven out of equilibrium. The electronic hopping amplitude is ramped down in time, resulting in an increased electr…
