Abstract: Strongly correlated impurities immersed in a Bose-Einstein condensate (BEC) can form a periodic structure of tightly localized single atoms due to competing inter- and intra-species interactions, leading to a self-organized pinned state. In this work, we show numerically that the impurities in the self-pinned state form a soliton-train, as a consequence of a BEC-mediated attractive self-interaction and ordering due to the exclusion principle. The dynamics of the impurities possess similar characteristics to bright matter-wave solitons as they appear in attractive BECs, however in the few impurities case, the detailed nature of collisions is determined by their quantum statistics.

Universal quantum dynamics of Bose polarons [0.0]
We measure the spectral properties and real-time dynamics of mobile impurities injected into a homogeneous Bose--Einstein condensate. We map out both attractive and repulsive branches of polaron quasiparticles. For near-resonant interactions the polarons are no longer well defined, but the universality still holds.

Frequency-resolved Purcell effect for the dissipative generation of steady-state entanglement [49.1574468325115]
We report a driven-dissipative mechanism to generate stationary entangled $W$ states among strongly-interacting quantum emitters placed within a cavity. The non-harmonic energy structure of the interacting ensemble allows this transition to be resonantly selected by the cavity. Evidence of this purely dissipative mechanism should be observable in state-of-the-art cavity QED systems in the solid-state.

Entanglement based observables for quantum impurities [0.0]
Quantum impurities exhibit fascinating many-body phenomena when the small interacting impurity changes the physics of a large noninteracting environment. Here, we harness an entanglement-based observable - the purity of the impurity - as a witness for the formation of strong correlations.

Unification of Random Dynamical Decoupling and the Quantum Zeno Effect [68.8204255655161]
We show that the system dynamics under random dynamical decoupling converges to a unitary with a decoupling error that characteristically depends on the convergence speed of the Zeno limit. This reveals a unification of the random dynamical decoupling and the quantum Zeno effect.

Weyl photons appear when two three-dimensional photonic bands with linear dispersion are degenerated at a single momentum point, labeled as Weyl point. We analyze the dynamics of a single quantum emitter coupled to a Weyl photonic bath as a function of its detuning with respect to the Weyl point.

Ionic polaron in a Bose-Einstein condensate [0.0]
The presence of strong interactions in a many-body quantum system can lead to a variety of exotic effects. We show that even in a relatively simple setup the competition of length scales gives rise to a highly correlated state. Our findings are directly relevant to experiments using hybrid atom-ion setups that have recently attained the ultracold regime.
