A numerical simulation of nonadiabatic electron excitation in the strong field regime: Linear polyenes.
Time-dependent Hartree-Fock theory has been used to study of the electronic optical response of a series of linear polyenes in strong laser fields. Ethylene, butadiene, and hexatriene have been calculated with 6-31G(d,p) in the presence of a field corresponding to 8.75 x 10(13) W/cm2 and 760 nm. Time evolution of the electron population indicates not only the pi electrons, but also lower lying ...
متن کاملNumerical simulation of nonadiabatic electron excitation in the strong-field regime. 3. Polyacene neutrals and cations.
The electron optical response for a series of linear polyacenes and their molecular ions (mono and dications) in strong laser fields was studied using time-dependent Hartree-Fock theory. The interactions of benzene, naphthalene, anthracene, and tetracene with pulsed fields at a frequency of 1.55 eV and intensities of 8.77 x 10(13), 3.07 x 10(13), 1.23 x 10(13), and 2.75 x 10(12) W/cm2, respecti...
متن کاملCoulomb explosion of large polyatomic molecules assisted by nonadiabatic charge localization.
The electron-nuclear dynamics of the Coulomb explosion of a large polyatomic molecule, anthracene, is probed using kinetic energy distributions of produced H+ ions. The kinetic energy release of ejected protons exceeds 30 eV for anthracene exposed to 10(14) W cm(-2), 800 nm pulses of 60 fs duration. We propose a strong-field charge localization model, based on nonadiabatic dynamics of charge di...
متن کاملAn overview of therapeutic applications of ultrasound based on synergetic effects with gold nanoparticles and laser excitation
Acoustic cavitation which occurs at high intensities of ultrasound waves can be fatal for tumor cells. The existence of dissolved gases and also the presence of nanoparticles (NPs) in a liquid, irradiated by ultrasound, decrease the acoustic cavitation onset threshold and the resulting bubbles collapse. On the other hand, due to unique capabilities and optical properties of gold nanoparticles (...
متن کاملLaser-driven nonadiabatic electron dynamics in molecules
In this review, we briefly summarize more than a decade of experimental and theoretical investigations regarding the nonadiabatic electron response to intense femtosecond duration laser fields in a variety of molecular systems. Historically, experimental signatures of nonadiabaticity have emerged readily in large, conjugated, or multi-electron systems, disrupting fragmentation behavior and modu...
