The degree of control achieved in ultracold atomic systems in optical lattices and the technological advances in high-Q cavities allow to reach experimentally the limit where both light and matter are fully quantum [1,2].It is possible to manipulate the atoms in the system via light, while inducing the competition and emergence of orders either spatially[3], dynamically[4], or magnetically[5,6]. It is possible to study the short and long range interaction competition to design the properties in the system[1,2]. This allows to study the competition between quantum many-body phases of analogs to real condensed matter electronic systems with possible uses to develop quantum technologies[5-6].
