Optimized Expansion for the Effective Ac
✍ A. Okopinska 📂 Article 📅 1993 🏛 Elsevier Science 🌐 English ⚖ 768 KB

The optimized expansion for the effective action in quantum field theory is discussed to second order. As an example we use the scalar quantum field theory with \(\lambda \phi^{4}\) interaction in one-dimensional space-time, which is equivalent to quantum mechanics of the anharmonic ascillator. The
