After decades of improvements in cooling techniques of several atomic species and in
finding methods for the achievement of stable quantum mixtures, the field is now ready for …

Impurities and polarons in bosonic quantum gases: a review on recent progress

F Grusdt, N Mostaan, E Demler, LAP Ardila - arxiv preprint arxiv …, 2024 - arxiv.org
This review describes the field of Bose polarons, arising when mobile impurities are
immersed into a bosonic quantum gas. The latter can be realized by a Bose-Einstein …

Observation of a molecular bond between ions and Rydberg atoms

N Zuber, VSV Anasuri, M Berngruber, YQ Zou… - Nature, 2022 - nature.com
Atoms with a highly excited electron, called Rydberg atoms, can form unusual types of
molecular bonds,,–. The bonds differ from the well-known ionic and covalent bonds, not only …

Interactions mediated by atoms, photons, electrons, and excitons

R Paredes, G Bruun, A Camacho-Guardian - Physical Review A, 2024 - APS
Interactions between quasiparticles mediated by a surrounding environment are ubiquitous
and lead to a range of important effects from collective modes of low-temperature quantum …

Many-body bound states and induced interactions of charged impurities in a bosonic bath

GE Astrakharchik, LAP Ardila, K Jachymski… - Nature …, 2023 - nature.com
Induced interactions and bound states of charge carriers immersed in a quantum medium

Ionic polaron in a Bose-Einstein condensate

GE Astrakharchik, LAP Ardila, R Schmidt… - Communications …, 2021 - nature.com
The presence of strong interactions in a many-body quantum system can lead to a variety of
exotic effects. Here we show that even in a comparatively simple setup consisting of a …

Mediated interaction between ions in quantum degenerate gases

S Ding, M Drewsen, JJ Arlt, GM Bruun - Physical Review Letters, 2022 - APS
We explore the interaction between two trapped ions mediated by a surrounding quantum
degenerate Bose or Fermi gas. Using perturbation theory valid for weak atom-ion …

Long-range Rydberg-atom–ion molecules of Rb and Cs

A Duspayev, X Han, MA Viray, L Ma, J Zhao… - Physical Review …, 2021 - APS
We propose a novel type of Rydberg dimer, consisting of a Rydberg-state atom bound to a
distant positive ion. The molecule is formed through long-range electric-multipole interaction …

Universal aspects of a strongly interacting impurity in a dilute Bose condensate

P Massignan, N Yegovtsev, V Gurarie - Physical review letters, 2021 - APS
We study the properties of an impurity immersed in a weakly interacting Bose gas, ie, of a
Bose polaron. In the perturbatively tractable limit of weak impurity-boson interactions many …
