On Wednesday the 18th of September a joint CHAMPS and Leeds Physical Chemistry seminar “Quantum Trajectories in Phase Space” took place in Leeds . The talk was given by Prof Craig Martens from University of California, Irvine. Although it is a physical/computational chemistry seminar it was of general interest, as it was focused on unusual formulation of quantum mechanics. We almost always think about quantum mechanics in terms of wave function and waves of probability, but there are other ways of looking at it. But Prof Martens presented one an approach, in which quantum mechanics is formulated very similar to classical mechanics, with the difference that neighbouring classical trajectories are not independent. They are entangled and push each other in a very specific way, as if there were many parallel worlds interacting with each other. The talk was attended not only by physicist, mathematicians and computational chemists, but also by a number of experimental organic and inorganic chemists.
