- Descrição
- 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 non-local ''Hamiltonian'' theory on the LF in view of the ''constraint equations'' on the phase space, which relate the bosonic condensates to the on-zero modes. This new ingredient is useful to describe the ''spontaneous symmetry breaking'' on the LF. The instability of the symmetric phase in two dimensional scalar theory when the coupling constant grows is shown in the LF theory renormalized to one loop order. ''Chern-Simons gauge theory'', regarded to describe excitations with fractional statistics, is quantized in the light-cone gauge and a simple LF Hamiltonian obtained which may allow us to construct renormalized theory of ''anyons''.
