Tunable Polarons in Bose-Einstein Condensates

open access: yesScientific Reports, 2017
A toolbox for the quantum simulation of polarons in ultracold atoms is presented. Motivated by the impressive experimental advances in the area of ultracold atomic mixtures, we theoretically study the problem of ultracold atomic impurities immersed in a ...

Quantum simulations with bilayer 2D Bose gases in multiple-RF-dressed potentials [PDF]

open access: yesAVS Quantum Science
Multiple-RF (MRF) dressing allows trapping of ultracold atoms in novel spatial geometries, such as highly controllable bilayer structures for two-dimensional (2D) ultracold gases, providing unique opportunities for the investigation of 2D quantum systems

In situ measurement of the dynamic structure factor in ultracold quantum gases [PDF]

open access: yes, 2011
We propose an experimental setup to efficiently measure the dynamic structure factor of ultracold quantum gases. Our method uses the interaction of the trapped atomic system with two different cavity modes, which are driven by external laser fields.

Coherence, Transport, and Chaos in 1D Bose–Hubbard Model: Disorder vs. Stark Potential

open access: yesFortschritte der Physik, Volume 73, Issue 11, November 2025.
Quantum coherence and criticality in finite Bose–Hubbard chains are investigated using exact diagonalization. Thermal fluctuations, Stark potential, and disorder reshape coherence, visibility, and superfluid response. Finite‐size systems show signatures of quantum criticality, with disorder suppressing global superfluidity but preserving local ...

Microelectromagnets for trapping and manipulating ultracold atomic quantum gases [PDF]

open access: yesApplied Physics Letters, 2002
We describe the production and characterization of microelectromagnets made for trapping and manipulating atomic ensembles. The devices consist of seven fabricated parallel copper conductors 3 μm thick, 25 mm long, with widths ranging from 3 to 30 μm, and are produced by electroplating a sapphire substrate.
