Temperature dependence of an Efimov resonance in
Lars J. Wacker, Nils B. Jørgensen, Kristoffer T. Skalmstang +3
Ultracold atomic gases are an important testing ground for understanding few-body physics. In particular, these systems enable a detailed study of the Efimov effect. We use ultraco…
Time-of-flight expansion of binary Bose-Einstein condensates at finite temperature
Kean Loon Lee, Nils B. Jørgensen, Lars J. Wacker +4
Ultracold quantum gases provide a unique setting for studying and understanding the properties of interacting quantum systems. Here, we investigate a multi-component system of $^{8…
A simple laser locking system based on a field-programmable gate array
Nils B. Jørgensen, Danny Birkmose, Kristian Trelborg +5
Frequency stabilization of laser light is crucial in both scientific and industrial applications. Technological developments now allow analog laser stabilization systems to be repl…
Phase Separation and Dynamics of two-component Bose-Einstein condensates
Kean Loon Lee, Nils B. Jørgensen, I-Kang Liu +3
The miscibility of two interacting quantum systems is an important testing ground for the understanding of complex quantum systems. Two-component Bose-Einstein condensates enable t…
Observation of Attractive and Repulsive Polarons in a Bose-Einstein Condensate
Nils B. Jørgensen, Lars Wacker, Kristoffer T. Skalmstang +5
The problem of an impurity particle moving through a bosonic medium plays a fundamental role in physics. However, the canonical scenario of a mobile impurity immersed in a Bose-Ein…
Universal three-body physics in ultracold KRb mixtures
L. J. Wacker, N. B. Jørgensen, D. Birkmose +5
Ultracold atomic gases have recently become a driving force in few-body physics due to the observation of the Efimov effect. While initially observed in equal mass systems, one exp…
Tunable dual-species Bose-Einstein condensates of K and Rb
L. Wacker, N. B. Jørgensen, D. Birkmose +6
We present the production of dual-species Bose-Einstein condensates of and . Preparation of both species in the $\left| F=1,m_F=-1 \right\rangle…
