What is it about?
Controlling atomic and molecular collisions by exploiting interference between identical scattering pathways seems exotic and even impossible at room temperature. In this work, I point out that at very cold temperatures, it is possible to use electric fields to make desired collision channels indistinguishable and therefore susceptible to coherent control tools. I choose a specific atomic collision process (Li + Cs) to illustrate the effect.

Perspectives
This paper marked my debut in professional scientific work. Although I later found ways to make the work much better and more widely applicable, I am very fond of this paper because it suggests a feasible solution to decade old problem in the field of coherent control, a fact that was recognized by the founder of that field!
