Vacuum Structures in Hamiltonian Light-Front Dynamics
Hamiltonian light-front dynamics of quantum fields may provide a useful approach to systematic non-perturbative approximations to quantum field theories. We investigate inequivalent Hilbert-space representations of the light-front field algebra in which the stability group of the light-front is implemented by unitary transformations. The Hilbert space representation of states is generated by th...
متن کاملLight - front vacuum and instantons in two dimensions
We review several aspects of Yang-Mills theory (YMT) in two dimensions, related to its perturbative and topological properties. Consistency between light-front and equal-time formulations is thoroughly discussed.
متن کاملLight-front Quantized Chiral Schwinger Model and Its Vacuum Structure
The bosonized Chiral Schwinger model (CSM) is quantized on the light-front (LF). The physical Hilbert space of CSM is obtained directly once the constraints on the LF phase space are eliminated. The discussion of the degenerate vacua and the absence in the CSM of the θ-vacua, as found in the Schwinger model (SM), becomes straightforward. The differences in the structures of the the mass excitat...
متن کاملLight - Front Dynamics and Light - Front Qcd
In this article, I will try to address some aspects of nonperturbative QCD. The theory of nonperturbative QCD (at the hadronic scale) has indeed not been well defined at the present time. Firstly, how much we can understand about the real theory of the strong interaction from the canonical QCD structure is totally unknown. Secondly, there are in the literature many models or effective theories ...
متن کاملMuch Ado about Nothing: Vacuum and Renormalization on the Light-front
In the first part of my lectures, I will use the example of deep-inelastic scattering to explain why light-front coordinates play a distinguished role in many high energy scattering experiments. After a brief introduction into the concept of light-front quantization, I will show that the vacuum for any light-front Hamiltonian is trivial, i.e. the same as for non-interacting fields. In the rest ...
