Extreme Ultrafast Dynamics of the Refractive Index in Transparent Conductive Oxides: Theory and Experiment
Noa Konforty, Graham G. Brown, Ohad Segal +5
Recent experiments in transparent conductive oxides (TCOs) have revealed light-induced order-unity variations in the refractive index occurring at extreme time scales, as short as…
Effects of Zero-Point Motion in the High Harmonic Generation Spectrum of Solids
Aday Cárdenas, David N. Purschke, Graham G. Brown +3
The interpretation of high-harmonic generation (HHG) in solids typically relies on phenomenological dephasing times far shorter than what is expected from microscopic scattering pr…
Unambiguous discrimination of high harmonic generation mechanisms in solids
Graham G. Brown, Rui E. F. Silva, Ãlvaro Jiménez-Galán +2
Using real-space view of high harmonic generation (HHG) in solids, we develop a physically transparent and gauge-invariant approach for distinguishing intraband and interband HHG m…
Semiconductor Wannier equations: a real-time, real-space approach to the nonlinear optical response in crystals (ATATA)
Eduardo B. Molinero, Bruno Amorim, Misha Ivanov +6
We develop the semiconductor Wannier equations (SWEs), a real-time, real-space formulation of ultrafast light-matter dynamics in crystals, by deriving the equations of motion for t…
Generation of massively entangled bright states of light during harmonic generation in resonant media
Sili Yi, Nikolai D. Klimkin, Graham Gardiner Brown +4
At the fundamental level, full description of light-matter interaction requires quantum treatment of both matter and light. However, for standard light sources generating intense l…
