Charges in light cones and quenched infrared radiation
Detlev Buchholz, Fabio Ciolli, Giuseppe Ruzzi +1
The creation of electrically charged states and the resulting electromagnetic fields are considered in space-time regions in which such experiments can actually be carried out, nam…

Twisting factors and fixed-time models in quantum field theory
Ezio Vasselli
We construct a class of fixed-time models in which the commutations relations of a Dirac field with a bosonic field are non-trivial and depend on the choice of a given distribution…

Twisted tensor products of field algebras
Ezio Vasselli
Let A be a C*-algebra, h a Hilbert space and C the CAR algebra over h. We construct a twisted tensor product of A by C such that the two factors are not necessarily one in the rela…
