Three-dimensional real-space electron dynamics in graphene driven by strong laser fields
S. Li, M. Tani, A. Hashmi +1
We theoretically investigate the three-dimensional (3D) electron dynamics of graphene in real space under strong laser fields using time-dependent density functional theory (TDDFT)…
Control of ion-photoelectron entanglement and coherence via Rabi oscillations
Kenichi L. Ishikawa, Kevin C. Prince, Kiyoshi Ueda
We report a theoretical investigation of photoionization by a pair of coherent, ultrashort fundamental and second-harmonic extreme-ultraviolet pulses, where the photon energies are…
Observation and Control of Laser-Enabled Auger Decay
D. Iablonskyi, K. Ueda, Kenichi L. Ishikawa +21
Single photon laser enabled Auger decay (spLEAD) has been redicted theoretically [Phys. Rev. Lett. 111, 083004 (2013)] and here we report its first experimental observation in neon…
Photoelectron Angular Distributions for Two-photon Ionization of Helium by Ultrashort Extreme Ultraviolet Free Electron Laser Pulses
R. Ma, K. Motomura, K. L. Ishikawa +19
Phase-shift differences and amplitude ratios of the outgoing and continuum wave packets generated by two-photon ionization of helium atoms are determined from the photoelec…
Competition of resonant and nonresonant paths in resonance-enhanced two-photon single ionization of He by an ultrashort extreme-ultraviolet pulse
Kenichi L. Ishikawa, Kiyoshi Ueda
We theoretically study the pulse-width dependence of the photoelectron angular distribution (PAD) from the resonance-enhanced two-photon single ionization of He by femtosecond ($\l…
Fine-scale oscillations in the wavelength- and intensity-dependence of high-harmonic generation: connection with channel closings
K. L. Ishikawa, K. Schiessl, E. Persson +1
We investigate the connection of recently identified fine-scale oscillations in the dependence of the yield of the high-harmonic generation (HHG) on wavelength lambda of a few-cycl…
