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 …

Interacting quantum systems in the chaotic domain are at the core of various ongoing
studies of many-body physics, ranging from the scrambling of quantum information to the …

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 decoupling of spin and density dynamics is a remarkable feature of quantum one-
dimensional many-body systems. In a few-body regime, however, little is known about this …

We study the ground state and excitations of a one-dimensional trapped polarized Fermi gas
interacting with a single impurity. First, we study the tunneling dynamics of the impurity …

In this paper we study a mixed system of bosons and fermions with up to six particles in total.
All particles are assumed to have the same mass. The two-body interactions are repulsive …

The single-particle spectral function of a strongly correlated system is an essential ingredient
to describe its dynamics and transport properties. We develop a method to evaluate exactly …

We investigate one-dimensional harmonically trapped two-component systems for repulsive
interaction strengths ranging from the non-interacting to the strongly interacting regime for …

This article investigates the properties of a few interacting particles trapped in a few wells
and how these properties change under adiabatic tuning of interaction strength and interwell …

For one-dimensional systems with delta-contact interactions, the convergence of the exact-
diagonalization method is tested with a basis of harmonic oscillator eigenfunctions with …
