ITMO University researchers have demonstrated that individual atoms can be transformed into polaritons—quantum particles that are a mixture of matter and light, which are transmitted via optical fibers.

Elsevier stands against racism and discrimination and fully supports the joint commitment for action in inclusion and diversity in publishing. But while electrons are the charge carriers in metal wires, the charge carriers in other circuits can be positive charges, negative charges or both. Thus, these negatively charged electrons move in the direction opposite the electric field. Once production of your article has started, you can track the status of your article via Track Your Accepted Article. Physics Open welcomes research from all main areas in physics and related areas – whether that be applied, experimental or theoretical physics in nature. Why is the universe more partial to matter than antimatter?
