Fermions and Condensates on the Light-Front
  Light-Front quantization is one of the most promising and physical tools towards studying deep inelastic scattering on the basis of quark gluon degrees of freedom. The simplified vacuum structure (nontrivial vacuum effects can only appear in zero-mode degrees of freedom) and the physical basis allows for a description of hadrons that stays close to intuition. I am reviewing recent progress in understanding the deep connection between renormalization of light-front Hamiltonians, effective light-front Hamiltonians and nontrivial vacuum condensates.
