,Feynman’s Path Integral Formulation of Schrödinger’s Wave Mechanics,blems; on the one hand, analytical solutions are only possible in very simple cases, and on the other hand, numerical calculations are extremely computer intense. However, path integrals often allow an approximate solution for physical processes, such as phase transitions, where perturbative methods fail.

Quantum Theory of Free Electromagnetic Fields,To account for quantum effects the Maxwell equations have to be quantized. We are thus led to quantum electrodynamics. Quantum electrodynamics also deals with the quantization of the electron—positron field, the pion field, and other fields and describes their interaction with the quantized electrom

Quantum Fields with Interaction,of the free fields and to introduce their interaction suitably. We have already come across the interaction between charged particles and photons. In the following we elaborate on how this well-known system is completely described from the field-theoretical point of view, i.e. in the language of sec

Nonrelativistic Quantum Field Theory of Interacting Particles and Its Applications,cribed within the framework of second quantization. Now we will extend this formalism with respect to particles interacting with each other. First, we construct an additional term in the Hamiltonian, which describes the potential interaction energy .(.′) between two particles at positions . and .′,
