PP 1840: Diatomic Molecules in Intense Laser Fields (SP of QUTIF)
Already in the past diatomic molecules have played a prominent role in understanding molecular processes. Therefore, an existing theoretical approach for the description of diatomic molecules with two electrons (like molecular hydrogen) exposed to ultrashort intense laser fields should be extended to diatomic molecules with an arbitrary number of electrons. A number of different approaches beyond single-electron models should be implemented. With the aid of these codes simulations shall be performed that study the behaviour of diatomic molecules in shaped laser fields or sequences of laser pulses. This should allow for the verification of control schemes.
The aim of this project is the development of methods for describing many-electron diatomic molecules exposed to ultrashort intense laser fields beyond the single-active-electron approximation. These methods should be applied to investigate the ionization behaviour of diatomic molecules on femto- and attosecond time scales as a function of the shape of a single laser pulse or for pulse sequences. The final goal is a deeper understanding of the time-dependent response of molecular many-electron systems in ultrashort intense laser pulses and the development and theoretical verification of control schemes. A focus will be on processes that show signatures of electron-electron correlation. Different observables as total ion yields, alignment or orientation-dependent ion yields and emitted high-harmonic spectra, energy- and angular-resolved electron spectra, as well as different molecular fragments should be considered.
