Investigations of emergent symmetry breaking phenomena occurring in small finite-size
systems are reviewed, with a focus on the strongly correlated regime of electrons in two …

Interelectron interactions and correlations in quantum dots can lead to spontaneous
symmetry breaking of the self-consistent mean field, resulting in the formation of Wigner …

We study the dynamics of two strongly interacting bosons with an additional impurity atom
trapped in a harmonic potential. Using exact numerical diagonalization we are able to fully …

The yrast spectra (ie, the lowest states for a given total angular momentum) of quantum dots
in strong magnetic fields, are studied in terms of exact numerical diagonalization and …

Quantum atomic and molecular gases are flexible systems for studies of fundamental many-
body physics. They have traditionally been produced in harmonic electromagnetic traps and …

Mobile impurity atoms immersed in Bose–Einstein condensates provide a new platform for
exploring Bose polarons. Recent experimental advances in the field of ultracold atoms make …

The review considers the peculiarities of symmetry breaking and symmetry transformations
and the related physical effects in finite quantum systems. Some types of symmetry in finite …

Strongly interacting systems of dipolar bosons in three dimensions confined by harmonic
traps are analyzed using the exact path integral ground-state Monte Carlo method. By …

We study the ground state of a system of Bose hard spheres trapped in an isotropic
harmonic potential to investigate the effect of the interatomic correlations and the accuracy of …

Harmonically trapped ultracold atoms and H 4 e in nanopores provide different experimental
realizations of bosons in one dimension, motivating the search for a more complete …
