Shear-strain controlled high-harmonic generation in graphene

T Tamaya, H Akiyama, T Kato - Physical Review B, 2023 - APS
We propose a method for controlling the high-harmonic generation (HHG) with a high
dynamic range in single-layer graphene. We find that, by utilizing shear strain, a significant …

Photoionization and transient Wannier-Stark ladder in silicon: First-principles simulations versus Keldysh theory

TJY Derrien, N Tancogne-Dejean, VP Zhukov, H Appel… - Physical Review B, 2021 - APS
Nonlinear photoionization of dielectrics and semiconductors is widely treated in the

High-harmonic generation in GaAs beyond the perturbative regime

P **a, T Tamaya, C Kim, F Lu, T Kanai, N Ishii, J Itatani… - Physical Review B, 2021 - APS
The field-intensity dependence of high-harmonic generation in bulk gallium arsenide is
studied. We experimentally find the oscillatory behavior at high fields where a perturbative …

Dual resonant sum frequency generations from two-dimensional materials

Y Kim, H Kim, H Jang, JH Ahn, JD Lee - Nano letters, 2020 - ACS Publications
We propose dual resonant optical sum frequency generation (SFG), where the two most
singular resonances could be selected, and report for the monolayer (1L-) WSe2 when one …

High-harmonic generation (HHG) from the condensed matter phase holds promise to
promote future cutting-edge research in the emerging field of attosecond nanoscopy. The …

Piezo-optic effect of high-harmonic generation in semiconductors

T Tamaya, T Kato - Physical Review B, 2021 - APS
We theoretically investigate the piezo-optic effect of high-harmonic generation (HHG) in
shear-strained semiconductors. By focusing on a typical semiconductor, GaAs, we show that …
