Multilocal fermionization
Karl-Henning Rehren, Gennaro Tedesco
We present a simple isomorphism between the algebra of one real chiral Fermi field and the algebra of n real chiral Fermi fields. This isomorphism preserves the vacuum state. This…

Warped Convolutions, Rieffel Deformations and the Construction of Quantum Field Theories
Detlev Buchholz, Gandalf Lechner, Stephen J. Summers
Warped convolutions of operators were recently introduced in the algebraic framework of quantum physics as a new constructive tool. It is shown here that these convolutions provide…

A sharpened nuclearity condition for massless fields
Wojciech Dybalski
A recently proposed phase space condition which comprises information about the vacuum structure and timelike asymptotic behavior of physical states is verified in massless free fi…
