Probing of Core Excitons in Solid NaF with Polarization-Selective Attosecond Time-Resolved Four-Wave Mixing Spectroscopy
Kevin Gulu Xiong, Rafael Quintero-Bermudez, Vincent Eggers +3
Nonlinear Four-wave mixing processes are a powerful technique to unravel ultrafast dynamics in solid-state systems. Here, we employ attosecond four-wave mixing spectroscopy with on…

Background-free Tracking of Ultrafast Hole and Electron Dynamics with XUV Transient Grating Spectroscopy
Vincent Eggers, Rafael Quintero-Bermudez, Kevin Gulu Xiong +1
Extreme ultraviolet (XUV) transient absorption (TA) and transient reflectivity (TR) spectroscopies enable element-specific insights into attosecond-timescale processes in solids. X…
