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 …

Engineering impurity Bell states through coupling with a quantum bath

TD Anh-Tai, T Fogarty, S de María-García, T Busch… - Physical Review …, 2024 - APS
We theoretically demonstrate the feasibility of creating Bell states in multicomponent
ultracold atomic gases by solely using the ability to control the interparticle interactions via …

Collective excitations of a Bose–Einstein condensate of hard-core bosons and their mediated interactions: from two-body bound states to mediated superfluidity

M Santiago-García… - New Journal of …, 2023 - iopscience.iop.org
The exchange of collective modes has been demonstrated to be a powerful tool for inducing
superconductivity and superfluidity in various condensed matter and atomic systems. In this …

Medium-induced interaction between impurities in a Bose-Einstein condensate

M Drescher, M Salmhofer, T Enss - Physical Review A, 2023 - APS
We consider two heavy particles immersed in a Bose-Einstein condensate in three
dimensions and compute their mutual interaction induced by excitations of the medium. For …

Induced correlations between impurities in a one-dimensional quenched Bose gas

SI Mistakidis, AG Volosniev, P Schmelcher - Physical Review Research, 2020 - APS
We explore the time evolution of two impurities in a trapped one-dimensional Bose gas that
follows a change of the boson-impurity interaction. We study the induced impurity-impurity …

Crossover from attractive to repulsive induced interactions and bound states of two distinguishable Bose polarons

F Theel, SI Mistakidis, P Schmelcher - SciPost Physics, 2024 - scipost.org
We study the impact of induced correlations and quasiparticle properties by immersing two
distinguishable impurities in a harmonically trapped bosonic medium. It is found that when …

Quantum dynamics of a Bose polaron in a -dimensional Bose-Einstein condensate

MM Khan, H Terças, JT Mendonça, J Wehr… - Physical Review A, 2021 - APS
We study the quantum motion of an impurity atom immersed in a Bose-Einstein condensate
in arbitrary dimensions. It was shown, for all dimensions, that the Bogoliubov excitations of …

Slow dynamics of a mobile impurity interacting with an Anderson insulator

P Sierant, T Chanda, M Lewenstein, J Zakrzewski - Physical Review B, 2023 - APS
We investigate dynamics of a single mobile impurity immersed in a bath of Anderson
localized particles and focus on the regime of relatively strong disorder and interactions. In …

Bath-induced correlations enhance thermometry precision at low temperatures

G Planella, MFB Cenni, A Acin, M Mehboudi - Physical Review Letters, 2022 - APS
We study the role of bath-induced correlations in temperature estimation of cold bosonic
baths. Our protocol includes multiple probes, that are not interacting, nor are they initially …

Polarons and their induced interactions in highly imbalanced triple mixtures

K Keiler, SI Mistakidis, P Schmelcher - Physical Review A, 2021 - APS
We unravel the polaronic properties of impurities immersed in a correlated trapped one-
dimensional Bose-Bose mixture. This setup allows the impurities to couple either attractively …
