Compact canonical quantization on the light cone (DLCQ) is examined in the limit of infinite periodicity lenth L. Pauli Jordan commutators are found to approach continuum expressions with marginal non causal terms of order L−3/4 traced back to the handling of IR divergence through the elimination of zero modes. In contrast direct quantization in the(More)
The dynamics of the phase transition of the continuum Φ41+1-theory in Light Cone Quantization is reexamined taking into account fluctuations of the order parameter < Φ > in the form of dynamical zero mode operators (DZMO) which appear in a natural way via the Haag expansion of the field Φ(x) of the interacting theory. The inclusion of the DZM-sector changes(More)
Critical behaviour of the 2D scalar field theory in the LC framework is reviewed. The notion of dynamical zero modes is introduced and shown to lead to a non trivial covariant dispersion relation only for Continuous LC Quantization (CLCQ). The critical exponent η is found to be governed by the behaviour of the infinite volume limit under conformal(More)
