Ultracold chemistry: cold atoms and where to bind them
Ultra-cold physics takes a step further by considering bound molecular states in the same temperature regime. A discussion of ultra-cold atomic cooling for the purpose of studying both atomic and molecular configurations is given. The focus will be on optical cooling methods such as Doppler and Sisyphus cooling with additional ventures into magnetic trapping and variants of evaporative cooling. Radiative forces and the limits these methods provide will be included as we decrease the overall temperature of our materials. Once a basis for achieving cold atoms has been established, we move to consider the dipole-dipole interactions and the shape of van der Waal potentials. Later the shape is used to coax our atoms into bound molecular states in a process called Feshbach resonance which will include a qualitative and quantitative description. And finally, we conclude with the applications we can explore which involve fundamental physics, complex system simulation, and quantum control.
