Ultracold atoms simulate hard-to-observe matter-antimatter pair production

According to quantum electrodynamics, the theory describing interactions between light and electrically charged particles, a sufficiently strong electric field can, in principle, convert some of its energy into particles and their antimatter partners. A particle's antimatter partner has the same mass and, for electrically charged particles, the opposite electric charge.
