Query: Oscillon Lifetime in the Presence of Quantum Fluctuations   We consider the stability of oscillons in 2+1 space-time dimensions, in the
presence of quantum fluctuations. Taking the oscillon to be the inhomogeneous
mean field of a self-interacting quantum scalar field, we compare its classical
evolution to the evolution in the presence of quantum fluctuations. The
evolution of these and their back reaction onto the mean field is implemented
through the inhomogeneous Hartree approximation, in turn computed as a
statistical ensemble of field realizations. We find that although the lifetime
of the oscillon is dramatically reduced compared to the classical limit, the
regions of longevity are similar in the space of Gaussian initial
configurations.
