Thermalization and dissipation are key processes in evaporative cooling. For polar molecules, there are long-range dipolar interactions, and the trapping geometry can be in a lower dimension, 2D. How do these change the process of thermalization and dissipation? How do these two processes interplay with each other? More practically, can evaporative cooling be useful for polar molecules?
