    "abstract": "We have developed a novel method to describe superradiance and related\ncooperative and collective effects in a closed form. Using the method we derive\na two-atom master equation in which any complexity of atomic levels,\nsemiclassical coupling fields and quantum fluctuations in the fields can be\nincluded, at least in principle. As an example, we consider the dynamics of an\ninitially inverted two-level system and show how even such in a simple system\nphenomena such as the initial radiation burst or broadening due to\ndipole-dipole interactions occur, but it is also possible to estimate the\npopulation of the subradiant state during the radiative decay. Finally, we find\nthat correlation only, not entanglement is responsible for superradiance.",
