Understanding quantum mechanics with active particles

(Nanowerk News) The study of active particles is one of the fastest-growing areas of physics. With „active particles“ physicists refer to objects which move by themselves as a result of internal self-propulsion. These include living things such as bacteria and fish swimming, birds flying or humans walking around – as well as artificial nano-robots which can be inserted into the body to transport medication. What interests the experts in particular is the behaviour of systems involving many active particles so that they can understand, for example, birds swarming,…
