Physical Significance of ,. Application to the Free-Particle CaseThe general theory developed in Chap. 1 can be applied directly to the time-independent one-particle Schrödinger equation by making the substitutions .(.)→ℌ(.), λ → ., where ℌ(.) is the Hamiltonian. The formalism presented in Chap. 2, Sects. 2.1,2.2 is applicable to the time-dependent one-particle Schrödinger equation.

The poles of an appropriate analytic continuation of . in the complex .-plane can be interpreted as the energy (the real part of the pole) and the inverse lifetime (the imaginary part of the pole) of quasiparticles. The latter are entities that allow us to map an interacting system to a noninteracting one.
