Cold atomic gases have become a paradigmatic system for exploring fundamental physics,
which at the same time allows for applications in quantum technologies. The accelerating …

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 …

We explore the quench dynamics of a binary Bose–Einstein condensate crossing the
miscibility–immiscibility threshold and vice versa, both within and in particular beyond the …

We develop and apply the multi-layer multi-configuration time-dependent Hartree method for
bosons, which represents an ab initio method for investigating the non-equilibrium quantum …

We explore the dynamical transport of an impurity between different embedding majority
species, which are spatially separated in a double well. The transfer and storage of the …

The multilayer multiconfigurational time-dependent Hartree (MCTDH) in optimized second
quantization representation (oSQR) approach combines the tensor contraction scheme of …

A mixture of two kinds of identical bosons held in a harmonic potential and interacting by
harmonic particle–particle interactions is discussed. This is an exactly-solvable model of a …

Measure synchronization (MS) in a two-species bosonic Josephson junction (BJJ) is studied
based on semiclassical theory. Six different scenarios for MS, including two in the …

A simple theory for the tunneling of two cold atoms out of a trap in the presence of an
attractive contact force is developed. Two competing decay channels, for single-atom and …

The recently introduced multi-layer (ML) multi-configurational time-dependent Hartree
(MCTDH) in optimized second quantization representation (oSQR) approach combines the …
