Effective light-front quantization of scalar field theories and two-dimensional electrodynamics.

چکیده
We introduce a new method to include condensates in the light-cone Hamilto-nian. By using a Gaussian approximation to the ordinary vacuum in a theory close to the light front, we derive an effective Hamiltonian on the light cone, which has new terms reflecting the nontriviality of the vacuum. We demonstrate our method for scalar φ 4-theory and the massive Schwinger model.

A brief introduction to nonperturbative calculations in light-front QED
Abstract A nonperturbative method for the solution of quantum field theories is described in the context of quantum electrodynamics and applied to the calculation of the electron’s anomalous magnetic moment. The method is based on light-front quantization and Pauli–Villars regularization. The application to light-front QED is intended as a test of the methods in a gauge theory, as a precursor t...

Some basic topics in Light-Front (LF) quantized field theory are reviewed. Poincarè algebra and the LF Spin operator are discussed. The local scalar field theory of the conventional framework is shown to correspond to a nonlocal Hamiltonian theory on the LF in view of the constraint equations on the phase space, which relate the bosonic condensates to the non-zero modes. This new ingredient is ...
متن کاملThe 3d Effective Field Theory for Finite Temperature Scalar Electrodynamics
The effective field theory approach to high temperature field theory can be used to study the phase transition in theories with spontaneously broken symmetry. I construct a sequence of two effective three–dimensional field theories which are valid on successively longer distance scales for a specific model: model: N charged scalars coupled to a U(1) gauge field. The resulting effective Lagrangi...
متن کاملNambu - Goldstone Boson on the Light - Front ∗
Spontaneous breakdown of the continuous symmetry is studied in the framework of discretized light-front quantization. We consider linear sigma model in 3+1 dimension and show that the careful treatment of zero modes together with the regularization of the theory by introducing NG boson mass leads to the correct description of Nambu-Goldstone phase on the light-front. Recently the light-front (L...
متن کاملWilson Coefficient for Vacuum Condensate of Photons from Electrodynamics Photon Propagator
In the framework of the operator product expansion I provide a detailed evaluation of the contribution of the lowest photon condensate to the two-point photon Green function for four-dimensional spinor electrodynamics and three-dimensional scalar electrodynamics. Since the above mentioned condensate affects the part of the propagator contributing to physical amplitudes I suggest that this conde...
