Self-probed ptychography from semiconductor high-harmonic generation
We demonstrate a method to image an object using a self-probing approach based on semiconductor high-harmonic generation. On one hand, ptychography enables high1 ar X iv :2 20 6. 08 33 3v 1 [ ph ys
Enhanced high-order harmonics through periodicity breaks: from backscattering to impurity states
Backscattering of delocalized electrons has been recently established [ Phys.Rev.A as a mechanism to enhance high-order harmonic generation (HHG) in periodic systems with broken translational
Introduction to theory of high-harmonic generation in solids: tutorial
High-harmonic generation (HHG) in solids has emerged in recent years as a rapidly expanding and interdisciplinary field, attracting attention from both the condensed-matter and the atomic, molecular,
Topological edge-state contributions to high-order harmonic generation in finite flakes
Edge states play a major role in the electron dynamics of topological insulators as they are the only conducting part in such materials. In this work, we consider the Haldane model for a 2D

Observation of high-order harmonic generation in a bulk crystal
High-order harmonic generation is a nonlinear optical process that enables the creation of light pulses at frequencies much higher than that from a seed laser. The host medium for this interaction is

Laser waveform control of extreme ultraviolet high harmonics from solids.
TLDR
It is found that harmonics are delayed with respect to each other, yielding an atto-chirp, which depends on the laser field strength, and provides the foundation for attosecond pulse metrology based on solid-state harmonics and a new approach to studying sub-cycle dynamics in solids.

TLDR
Evidence for fluence amplification of self-guided pulses, increase of filamentation length, as well as a lowering of the input laser power necessary for filamentation is reported.
High-order-harmonic generation of a doped semiconductor
We investigate the high-order harmonic generation (HHG) in doped semiconductors. The HHG is simulated with the single-electron time-dependent Schr\"{o}dinger equation (TDSE). The results show that

A three step model for high harmonic generation from impurities in solids is developed. The process is found to be similar to high harmonic generation in atomic and molecular gases with the main
Theoretical analysis of high-harmonic generation in solids.
TLDR
The analysis indicates that the interband current neglected so far is the dominant mechanism for HHG, and saddle point analysis in the Keldysh limit yields an intuitive picture of interband HHG in solids similar to atomic HHG.

TLDR
It is found that ions can produce harmonics comparable in strength to those obtained from neutrals, and that the emission extends to much higher order.
