Atomic systems occupy a beautiful niche in physics. Atoms and molecules are often simple enough to be quite tractable theoretically while offering a rich internal structure and a varied array of interactions that may be probed and controlled by the experimentalist. Understanding these details is of course imperative for learning about the atoms themselves. However, our control over these systems also gives us an opportunity to use them as tools for exploring phenomena in other areas of physics and chemistry, ranging from condensed matter to cosmology. Furthermore, when properly harnessed atoms find a host of technological applications, such as quantum-limited sensing or as reference oscillators for the atomic clocks that underpin the Global Positioning System.
My particular interest is in applying simple systems of trapped atomic to quantum simulation, in which a trapped-ion crystal is used to emulate the behavior of a more complicated quantum system. To do this, we trap calcium ions using DC and RF electric fields generated by a surface-electrode Paul trap, and use lasers to control, manipulate, and read-out the quantum states of the trapped ions.
