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 group currently has two experiments, the Sodium atom circuits experiment and the ultracold Strontium experiment. Both experiments are located at the Joint Quantum Institute located on the UMD. and use ultracold atomic gases to study many-body physics. The atom circuits experiment is currently focused on studying superfluidity and analogs of both superconducting electronics and cosmological physics, 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.
