title: Quatron-polaritons: charged quasi-particles having the bosonic statistics.
abstract: Negatively charged quatrons are quasi-particles composed of a hole and three electrons in a semiconductor. In bulk semiconductors they are unstable. We show that they become stable if coupled to light in specially designed triple quantum layer structures embedded in microcavities. Due to an extremely small effective mass, charged quatron-polaritons can form a superfluid at high temperatures. This opens up a breathtaking perspective on optically induced and controlled superconductivity at room temperature.
