Femtosecond nonlinear spectroscopy is the main tool for the time-resolved detection of
photophysical and photochemical processes. Since most systems of chemical interest are …

In this Colloquium, the wave-function-based multiconfigurational time-dependent Hartree
approaches to the dynamics of indistinguishable particles (MCTDH-F for fermions and …

The simulations of spectroscopy and quantum dynamics are of vital importance to the
understanding of the electronic processes in complex systems, including the …

Electronic and/or vibronic coherence has been found by recent ultrafast spectroscopy
experiments in many chemical, biological, and material systems. This indicates that there …

We present how to compute vibrational eigenstates with tree tensor network states (TTNSs),
the underlying ansatz behind the multilayer multiconfiguration time-dependent Hartree (ML …

The low-rank approximation is a complexity reduction technique to approximate a tensor or
a matrix with a reduced rank, which has been applied to the simulation of high dimensional …

The time dependent density matrix renormalization group (TD-DMRG) has become one of
the cutting edge methods of quantum dynamics for complex systems. In this paper, we …

We introduce and describe the multiconfigurational time-depenent Hartree for
indistinguishable particles (MCTDH-X) software, which is hosted, documented, and …

In this paper, we develop quantum dynamical methods capable of treating the dynamics of
chemically reacting systems in an optical cavity in the vibrationally strong-coupling (VSC) …

We analyze and discuss convergence properties of a numerically exact algorithm tailored to
study the dynamics of interacting two-dimensional lattice systems. The method is based on …
