Query: Low-energy effective quantum field theoretic description of excitations
  about soliton configurations   Solitons are the classical field configurations connecting two trivial vacua.
These are also the solutions of classical field equations of motion with
particle-like properties. Moreover, they are localized in space, having finite
energy, and are stable against decay into radiation. The coherent state
description of kink-solitons is discussed in the present article. Further, the
relation between topological solitons and occupation numbers corresponding to
low momentum excitations are also discussed coherently. The description of the
low energy excitations about solitons in quantum field theory is the main theme
of this article. Further, a few physical observables, namely some low order
correlation functions, are computed up to certain integral forms. Furthermore,
we have shown that it is possible to detect the presence of soliton-like
classical configurations in many-particle systems from the nature of the
one-point function and non-conservation of momentum feature of one-point,
two-point and three-point functions in this low-energy effective field theory
of these excitations.
