要旨訳： （近日中に公開） Abstract： We theoretically study the photoelectron angular distribution (PAD) from the two-photon single ionization of H and He by femtosecond and attosecond extreme-ultraviolet pulses, based on the time-dependent perturbation theory and simulations with the full time-dependent Schrodinger equation. The PAD is formed by the interference of the s and d continuum wave packets, and, thus, contains the information on ...

要旨訳： （準備中） Abstract： We demonstrate the generation and real-time observation of the vibrational wave packet of D+2 by using a sub-10-fs extreme UV high-harmonic pump pulse and a three-color probe laser pulse whose wavelength ranges from near-IR to vacuum UV. This multicolor pump–probe scheme can provide us with a powerful experimental tool for investigating a variety of wave packets evolving with a time scale of \sim20  fs. Sourc...

要旨訳： （準備中） Abstract： We present time-resolved ab initio study of the attosecond dynamics of electron-electron correlation during single-electron, single XUV-photon ionization of an excited helium atom. We identify multiple time scales in these dynamics, caused by the interplay of the initial shake-up excitation with the excitation cascades induced by the postionization interaction of the outgoing electron with the core. The time s...

要旨訳： （準備中） Abstract： The interaction between platelets and vessel walls in the primary aggregation of platelets was investigated using kinetic Monte Carlo simulation for the multiscale simulation of thrombus formation. The kinetic Monte Carlo lattice model of a platelet surface with glycoprotein Ibα (GPIbα) localization region was simulated by considering 3 types of events: GPIbα diffusion, GPIbα-von Willebrand factor (vWF) bond f...

要旨訳： （準備中） Abstract： Ultrafast atomic processes, such as excitation and ionization occurring on the femtosecond or shorter time scale, were explored by employing attosecond high-harmonic pulses. With the absorption of a suitable high-harmonic photon a He atom was ionized, or resonantly excited with further ionization by absorbing a number of infrared photons. The electron wave packets liberated by the two processes generated an in...

要旨訳： （準備中） Abstract： 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 (& 20 fs) extreme- ultraviolet pulses, based on the time-dependent perturbation theory and simulations with the full time- dependent Schro ̈dinger equation. In particular, we focus on the competition between resonant and nonr...

要旨訳： （準備中） Abstract： We analyze the doubly differential electron distribution in atomic above-threshold ionization by a linearly-polarized short-laser pulse. We generalize the one-dimensional (1D) simple man’s model (SMM) of Arbó et al., to a three dimensional (3D) description by using the saddle-point approximation (SPA). We prove that the factorization of the photoelectron spectrum in terms of intracycle and intercycle interfere...
