“…The problem in this case is that, as the ϕ(x)-state becomes more certain, the scalar field momentum state becomes more uncertain. The result is a divergent increase in the energy density [5,6]. …”

“…The formulation of CSL, in terms of a stochastic differential equation, invites a straightforward generalization to relativistic quantum field theory (QFT), but it is well known that this results in physically unacceptable divergent behavior [5,6]. Here we shall address the question of how these infinities can be avoided.…”

“…[19][20][21]), the coefficient of δ 3 ( 0) is a nontrivial operator and not a constant. The δ 3 ( 0) singularity is a direct result of the local derivative structure of the drift term, and we have not found a mechanism to cancel it within the standard stochastic differential equation and quantum field theory framework discussed here.…”

“…The fact that we can't expect a collapse theory to produce eigenstates of local observables led Ghirardi et al (1990) to propose, as a criterion for attribution of local objective properties to systems, one based one approximations to eigenstates. 8 We think that the appropriate attitude is the following: when considering a local observable A with its associated support we say that an individual system has the objective property a (a being an eigenvalue of A), only when the mean value of P a is extremely close to one, when evaluated on all spacelike hypersurfaces containing the support of A (p. 1310).…”
