Extreme Ultraviolet High-Harmonic Interferometry of Excitation-Induced Bandgap Dynamics in Solids
Lisa-Marie Koll, Simon Vendelbo Bylling Jensen, Pieter J. van Essen +9
Interferometry is a fundamental technique in physics, enabling precise measurements through the interference of waves. High-harmonic generation (HHG) in solids has emerged as a pow…
