New study reveals the ins and outs of diffusion with stochastic resetting

Prof. Roichman and Dr. Reuveni, along with the Ofir Tal-Friedman, Dr. Arnab Pal and Dr. Amandeep Sekhon, developed an experimental system to study diffusion with stochastic resetting and discovered limitations on the energy cost of resetting in the real world.

The system they developed is first of its kind. It allows one to track a particle that performs a diffusion, and reset its position using optical tweezers. These tweezers are actually laser beams used to move and manipulate microscopic particles, similar to the tractor beam that appeared in the TV series Star Trek. The tools developed in the research will also enable the study of stochastic resetting in multibody systems with interactions.
