We investigate transport dynamics of a single low-energy ionic impurity in a Bose-Einstein condensate. The impurity is implanted into the condensate starting from a single Rydberg excitation, which is ionized by a sequence of fast electric field pulses aiming to minimize the ion's initial kinetic energy. Using a small electric bias field, we study the subsequent collisional dynamics of the impurity subject to an external force. The fast ion-atom collision rate, stemming from the dense…

Pulsed Ion Microscope to Probe Quantum Gases
The advent of the quantum gas microscope allowed for the in situ probing of ultracold gaseous matter on an unprecedented level of spatial resolution. The study of phenomena on ever smaller length
Ionic polaron in a Bose-Einstein condensate
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 charged impurity in a

Nonadiabatic decay of Rydberg-atom–ion molecules
The decay of Rydberg-atom-ion molecules (RAIMs) due to non-adiabatic couplings between electronic potential energy surfaces is investigated. We employ the Born-Huang representation and perform
Probing Lorentz-Invariance-Violation Induced Nonthermal Unruh Effect in Quasi-Two-Dimensional Dipolar Condensates
The Unruh effect states an accelerated particle detector registers a thermal response when moving through the Minkowski vacuum, and this thermal phenomenon is believed to be inseparable from Lorentz
Analysis of Multipolar Linear Paul Traps for Ion–Atom Ultracold Collision Experiments
We evaluate the performance of multipole, linear Paul traps for the purpose of studying cold ion–atom collisions. A combination of numerical simulations and analysis based on the virial theorem is
Charged Polarons and Molecules in a Bose-Einstein Condensate.
The long-range nature of the ion-atom interaction gives rise to an intricate interplay between few- and many-body physics, which leads to the existence of several polaronic and molecular states due to the binding of an increasing number of bosons to the ion.
Dynamics of a trapped ion in a quantum gas: Effects of particle statistics
We study the quantum dynamics of an ion confined in a radiofrequency trap in interaction with either a Bose or spin-polarized Fermi gas. To this end, we derive quantum optical master equations in the
Interactions of Ions and Ultracold Neutral Atom Ensembles in Composite Optical Dipole Traps: Developments and Perspectives
Ion–atom interactions are a comparatively recent field of research that has drawn considerable attention due to its applications in areas including quantum chemistry and quantum simulations. In first
Long-Range Atom–Ion Rydberg Molecule: A Novel Molecular Binding Mechanism
We present a novel binding mechanism where a neutral Rydberg atom and an atomic ion form a molecular bound state at a large internuclear distance. The binding mechanism is based on Stark shifts and


A prototype probability package named APPL (A Probability Programming Language) is presented that can be used to manipulate random variables and examples illustrate its use.
