The light-front vacuum and dynamics
arXiv:nucl-th/0409049 · doi:10.1007/s00601-004-0103-x
Abstract
I give a quantum theoretical description of kinematically invariant vacuua on the algebra of free fields restricted to a light front and discuss the relation between the light-front Hamiltonian, P-, the vacuum, and Poincare invariance. This provides a quantum theoretical description of zero modes.
