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 report on the deterministic preparation of antiferromagnetic Heisenberg spin chains
consisting of up to four fermionic atoms in a one-dimensional trap. These chains are …

A fully operational loss-free quantum battery requires an inherent control over the energy
transfer process, with the ability of kee** the energy retained with no leakage. Moreover, it …

Spin chains are paradigmatic systems for the studies of quantum phases and phase
transitions, and for quantum information applications, including quantum computation and …

We investigate a temporal evolution of an impurity atom in a one-dimensional trapped Bose
gas following a sudden change of the boson-impurity interaction strength. Our focus is on …

We present a general form of the effective spin-chain model for strongly interacting atomic
gases with an arbitrary spin in one-dimensional (1D) traps. In particular, for high-spin …

Artificial neural networks have been successfully incorporated into the variational Monte
Carlo method (VMC) to study quantum many-body systems. However, there have been few …

We present a theoretical framework for describing an impurity in a trapped Bose system in
one spatial dimension. The theory handles any external confinement, arbitrary mass ratios …

The highly excited super-Tonks-Girardeau (sTG) gas was recently observed to be extremely
stable in the presence of a weak dipolar repulsion. Here we reveal the underlying reason for …
