The radiative behavior of ensembles of atoms in collective states, i.e., superradiance, has been studied in depth since the seminal paper by Dicke in 1954 (Phys. Rev. 93, 99), where he demonstrated that a group of entangled emitters is able to radiate with increased intensity and modified decay rates in particular directions. Here, we discuss the radiative characteristics and quantum properties of two coherently driven atoms coupled to a single-mode cavity, an ideal setup to investigate the basic aspects of collective behavior. We show that the system is able to exceed the free-space superradiant behavior of two atoms by orders of magnitude, a phenomenon which we call hyperradiance. We also study the phase control of the quantum statistics and find that a quantum version of the negative binomial distribution is able to characterize the photon distribution in the cavity and its quantum features. Our theoretical results could stimulate future experiments as the investigated system can be realized with current technology.
