Coherent phonon motions and ordered vacancy compound mediated quantum path interference in Cu-poor CuInGaSe (CIGS) with attosecond transient absorption
Hugo Laurell, Jonah R. Adelman, Elizaveta Yakovleva +7
In this study, coherent phonon motion is observed in bandgap excited CuInGaSe (CIGS) utilizing extreme ultraviolet (XUV) attosecond transient absorption spectro…

Entanglement Transfer in a Composite Electron-Ion-Photon System
Axel Stenquist, Jakob Nicolai Bruhnke, Felipe Zapata +1
We study how entanglement in photoionization is transferred from an electron-ion pair to an electron-photon pair by fluorescence. Time-resolved von Neumann entropies are used to es…

Giant counter-rotating oscillations on the attosecond timescale
Jakob Nicolai Bruhnke, Edvin Olofsson, Axel Stenquist +1
We predict an unexplored type of ultrastrong coupling between atoms and intense ultraviolet light that leads to giant population oscillations on the attosecond timescale. These cou…
