Ultracold gases, such as the Bose-Einstein condensates, can behave as fluids that exhibit the unusual rules of the quantum world.
Welcome to the Campbell Research Group
In recent years ultracold atomic gases have proven to be a powerful and versatile tool for studying a wide variety of physics.
Our research takes place in two separate laboratories: The Sodium atom circuits experiment, currently located on the NIST campus in Gaithersburg, and the ultracold Strontium experiment, located at the JQI, on the UMD campus. Both experiments use ultracold atomic gases to study many-body physics. The atom circuits experiment is currently focused on studying superfluidity and analogs of superconducting electronics, whereas the strontium experiment is focused on engineering and studying novel condensed matter systems.
At the JQI, we're currently building an apparatus to trap and cool Strontium atoms. Strontium has some nice atomic properties, which make it an ideal system to study. One main advantage is it has very narrow atomic transitions, which are relatively insensitive to electromagnetic surroundings.
