Query: Quantal corrections to mean-field dynamics including pairing   Extending the stochastic mean-field model by including pairing, an approach
is proposed for describing evolutions of complex many-body systems in terms of
an ensemble of Time-Dependent Hartree-Fock Bogoliubov trajectories which is
determined by incorporating fluctuations in the initial state. Non-linear
evolution of the initial fluctuations provides an approximate description of
quantal correlations and fluctuations of collective observables. Since the
initial-state fluctuations break the particle-number symmetry, the dynamical
description in which pairing correlations play a crucial role is greatly
improved as compare to the mean-field evolution. The approach is illustrated
for a system of particles governed by a pairing Hamiltonian.
