Population transfer between electronic molecular states can be effectively induced via the interaction with shaped laser pulses. Regarding a numerical example, it is demonstrated that perturbation theory, as is often applied in numerical simulations of field-matter interactions, might lead to divergences. The occurring error accumulating in the norm of the wavefunction can be decomposed into two contributions. The first one is a small numerical error, which is controllable by minimization of…

Quantum diffusion wave-function approach to two-dimensional vibronic spectroscopy.

The wave-packet approach, besides being an alternative technique to calculate the spectra, offers an intuitive insight into the dissipation dynamics and its relation to the 2D vibronic spectra.

Extended quantum jump description of vibronic two-dimensional spectroscopy.

Two-dimensional (2D) vibronic spectra are calculated for a model system involving two electronic molecular states and the influence of dissipation and dephasing is characterized using a wave function based method.

Fragment momentum distributions obtained from coupled electron-nuclear dynamics.

It is shown that a simultaneous excitation of two different electronic states results in further interferences which are related to electronic wave-packet dynamics on the attosecond time-scale and are modified by the electronic degree-of-freedom.

Numerical method for nonlinear optical spectroscopies: Ultrafast ultrafast spectroscopy.

A novel numerical method, called Ultrafast Ultrafast (UF2) spectroscopy, for calculating the nth-order wavepackets required for calculating n-wave mixing signals, and it is demonstrated that it is computationally more efficient than other methods in a wide range of use cases.

Two-dimensional vibronic spectroscopy of molecular predissociation

We calculate two-dimensional (2D) spectra reflecting the time-dependent electronic predissociation of a diatomic molecule. The laser-excited electronic state is coupled non-adiabatically to a
