Mechanisms of high harmonic generation in solids
A. Thorpe, N. Boroumand, A. M. Parks +2
The long standing issue of separating resonant from non-resonant processes in extreme nonlinear optics is resolved. The theoretical formalism is applied to high harmonic generation…
Wannier quasi-classical approach to high harmonic generation in semiconductors
Andrew M. Parks, Guilmot Ernotte, Adam Thorpe +4
We develop a quasi-classical theory of high harmonic generation in semiconductors based on an interband current that has been transformed from Bloch to Wannier basis. The Wannier q…
Multi-Band Petahertz Currents Resolved via High Harmonic Generation Spectroscopy
Ayelet Julie Uzan, Gal Orenstein, Álvaro Jiménez-Galán +13
Strong field driven electric currents in condensed matter systems open new frontiers in petahertz electronics. In this regime new challenges arise as the role of the band structure…
High harmonic generation tomography of impurities in solids: conceptual analysis
S. Almalki, A. Parks, G. Bart +3
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…
Explicit formulation of second and third order optical nonlinearity in the FDTD framework
Charles Varin, Rhys Emms, Graeme Bart +2
The finite-difference time-domain (FDTD) method is a flexible and powerful technique for rigorously solving Maxwell's equations. However, three-dimensional optical nonlinearity in…
MeV femtosecond electron pulses from direct-field acceleration in low density atomic gases
Charles Varin, Vincent Marceau, Pascal Hogan-Lamarre +3
Using three-dimensional particle-in-cell simulations, we show that few-MeV electrons can be produced by focusing tightly few-cycle radially-polarized laser pulses in a low-density…
