The dynamical properties of a one-dimensional system of two bosons escaping from an open potential well are studied in terms of the momentum distributions of particles. It is shown that the single- and two-particle momentum distributions undergo a specific transition as the interaction strength is tuned through the point where tunneling switches from the pair tunneling to the sequential one. Characteristic features in the momentum spectra can be used to quantitatively determine the… 
Two Rydberg-dressed atoms escaping from an open well
A comprehensive analysis of the dynamics of two Rydberg-dressed particles (bosons or fermions) tunneling from a potential well into open space is provided. We show that the dominant decay mechanism
Full counting statistics of the momentum occupation numbers of the Tonks-Girardeau gas
We compute the fluctuations of the number of bosons with a given momentum for the Tonks-Girardeau gas at zero temperature. We show that correlations between opposite momenta, which is an important
Capturing nonexponential dynamics in the presence of two decay channels
The most unstable quantum states and elementary particles possess more than a single decay channel. At the same time, it is well known that typically the decay law is not simply exponential.
One-dimensional mixtures of several ultracold atoms: a review.
TLDR
The recent advances on trapped Bose-Fermi mixtures are described, which allow for a theoretical combination of previous concepts, well illustrating the importance of quantum statistics and inter-particle interactions.
Imaginary-time mean-field method for collective tunneling
Background: Quantum tunneling in many-body systems is the subject of many experimental and theoretical studies in fields ranging from cold atoms to nuclear physics. However, theoretical description
Decay properties of unstable Tonks-Girardeau gases from a split trap
We study the decay properties of Tonks-Girardeau gases escaping from a double-well potential. Initially, the gases are constrained between two infinite $\delta$ barriers with an on-center

Dynamics of a few interacting bosons escaping from an open well
The dynamics of a few ultra-cold bosons tunneling from a one-dimensional potential well into open space is studied. In such a system several decay channels can be distinguished, each corresponding to
Tunneling decay of two interacting bosons in an asymmetric double-well potential: A spectral approach
We study the full-fledged microscopic dynamics of two interacting, ultracold bosons in a one- dimensional double-well potential, through the numerically exact diagonalization of the many-body
Tunneling dynamics of few bosons in a double well
We study few-boson tunneling in a one-dimensional double well. As we pass from weak interactions to the fermionization limit, the Rabi oscillations first give way to highly delayed pair tunneling
Pairing in few-fermion systems with attractive interactions.
TLDR
From the tunneling time scales, this work infer the differences in interaction energies of systems with different number of particles, which show a strong odd-even effect, similar to the one observed for neutron separation experiments in nuclei.

We study the decay of two repulsively interacting bosons tunnelling through a delta potential barrier by a direct numerical solution of the time-dependent Schrodinger equation. The solutions are

We study theoretically the few-body dynamics of atoms which leak out of a trap by tunneling through a thin barrier. We consider the two cases of bosons with strongly repulsive contact interactions

Spatial and momentum correlations are important in the analysis of the quantum states and different phases of trapped ultracold atom systems as a function of the strength of interatomic interactions.
Few-boson dynamics in double wells: from single-atom to correlated pair tunneling.
TLDR
This work investigates few-boson tunneling in a one-dimensional double well and finds that the tunneling dynamics of two atoms evolves from Rabi oscillations to correlated pair tunneling as the authors increase the interaction strength.
