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

Recent theoretical and experimental progress on studying one-dimensional systems of
bosonic, fermionic, and Bose–Fermi mixtures of a few ultracold atoms confined in traps is …

Understanding the real-time evolution of many-electron quantum systems is essential for
studying dynamical properties in condensed matter, quantum chemistry, and complex …

We report on an implementation of the multiconfigurational time-dependent Hartree method
(MCTDH) for spin-polarized fermions (MCTDHF). Our approach is based on a map** for …

The exactly solvable quantum many-particle model with harmonic one-and two-particle
interaction terms is extended to include time dependency. We show that when the external …

The experimental revolution in ultracold atomic gas physics over the past decades has
brought tremendous amounts of new insight to the world of degenerate quantum systems …

We investigate a trapped mixture of Bose–Einstein condensates consisting of a multiple
number of P species. To be able to do so, an exactly solvable many-body model is called …

Abstract The diffusion Monte Carlo method is applied to describe a trapped atomic Bose-
Einstein condensate at zero temperature, fully quantum mechanically and nonperturbatively …

The lecture notes on “Many-body Quantum Dynamics with MCTDH-X”, adapted from the
2023 Heidelberg MCTDH Summer School, provide an indepth exploration of the …

We consider an analytic way to make the interacting N-body problem tractable by using
harmonic oscillators in place of the relevant two-body interactions. The two-body terms of the …
