Query: Relativistic generalizations of gravity-induced localization models   Nonunitary versions of Newtonian gravity leading to wavefunction localization
admit natural special-relativistic generalizations. They include the first
consistent relativistic localization models. At variance with the unified model
of localization and gravity, the purely localizing version requires negative
energy fields, which however are less harmful than usual and can be used to
build ultraviolet-finite theories.
