Conjecture on nontrivial dynamical solutions. Solutions of this selection rule with $\alpha(k)\neq0$ become important.

In the relativistic particle and FLRW settings, let the physical Hilbert space decompose into positive- and negative-frequency sectors, with the representation reducible so that on…

Let the fermionic modes be subject to charge superselection, so that the locally available operations are restricted accordingly. Entanglement-swapping conjecture. The entanglement…

A model here means a chiral conformal field theory with charged representations and the associated particle-weight structure; an infraparticle is a particle-like excitation without…
