      abstract     = {A recently introduced theoretical framework for modeling
                      the dynamics of x-ray amplified spontaneous emission is
                      based on stochastic sampling of the density matrix of
                      quantum emitters and the radiation field, similarly to other
                      phase-space sampling techniques. While based on first
                      principles and providing valuable theoretical insights, the
                      original stochastic differential equations exhibit
                      divergences and numerical instabilities. Here, we resolve
                      this issue by accounting the stochastic components
                      perturbatively. The refined formalism accurately reproduces
                      the properties of spontaneous emission and proves
                      universally applicable for describing all stages of
                      collective x-ray emission in paraxial geometry, including
                      spontaneous emission, amplified spontaneous emission, and
                      the nonlinear regime. Through numerical examples, we analyze
                      key features of superfluorescence in a one-dimensional
                      approximation. Importantly, single realizations of the
                      underlying stochastic equations can be fully interpreted as
                      individual experimental observations of superfluorescence.},
