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…
Where charged sectors are localizable: a viewpoint from covariant cohomology
Fabio Ciolli, Giuseppe Ruzzi, Ezio Vasselli
Given a Haag-Kastler net on a globally hyperbolic spacetime, one can consider a family of regions where quantum charges are supposed to be localized. Assuming that the net fulfils…
On the Thermodynamics of Particles Obeying Monotone Statistics
Fabio Ciolli, Francesco Fidaleo, Chiara Marullo
The aim of the present paper is to provide a preliminary investigation of the thermodynamics of particles obeying monotone statistics. To render the potential physical applications…
Gauss's law, the manifestations of gauge fields, and their impact on local observables
Detlev Buchholz, Fabio Ciolli, Giuseppe Ruzzi +1
Within the framework of the universal algebra of the electromagnetic field, the impact of globally neutral configurations of external charges on the field is analyzed. External cha…
Spectral actions for q-particles and their asymptotics
Fabio Ciolli, Francesco Fidaleo
For spectral actions consisting of the average number of particles and arising from open systems made of general free -particles (including Bose, Fermi and classical ones corres…
On the Thermodynamics of the q-Particles
Fabio Ciolli, Francesco Fidaleo
Since the grand partition function for the so-called -particles (i.e.,\ quons), , cannot be computed by using the standard 2nd quantisation technique involving…
The universal algebra of the electromagnetic field III. Static charges and emergence of gauge fields
Detlev Buchholz, Fabio Ciolli, Giuseppe Ruzzi +1
A universal C*-algebra of gauge invariant operators is presented, describing the electromagnetic field as well as operations creating pairs of static electric charges having opposi…
Relative entropy and curved spacetimes
Fabio Ciolli, Roberto Longo, Alessio Ranallo +1
Given any half-sided modular inclusion of standard subspaces, we show that the entropy function associated with the decreasing one-parameter family of translated standard subspaces…
The information in a wave
Fabio Ciolli, Roberto Longo, Giuseppe Ruzzi
We provide the notion of entropy for a classical Klein-Gordon real wave, that we derive as particular case of a notion entropy for a vector in a Hilbert space with respect to a rea…
Linking numbers in local quantum field theory
Detlev Buchholz, Fabio Ciolli, Giuseppe Ruzzi +1
Linking numbers appear in local quantum field theory in the presence of tensor fields, which are closed two-forms on Minkowski space. Given any pair of such fields, it is shown tha…
The universal C*-algebra of the electromagnetic field II. Topological charges and spacelike linear fields
Detlev Buchholz, Fabio Ciolli, Giuseppe Ruzzi +1
Conditions for the appearance of topological charges are studied in the framework of the universal C*-algebra of the electromagnetic field, which is represented in any theory descr…
The universal C*-algebra of the electromagnetic field
Detlev Buchholz, Fabio Ciolli, Giuseppe Ruzzi +1
A universal C*-algebra of the electromagnetic field is constructed. It is represented in any quantum field theory which incorporates electromagnetism and expresses basic features o…
QED Representation for the Net of Causal Loops
Fabio Ciolli, Giuseppe Ruzzi, Ezio Vasselli
The present work tackles the existence of local gauge symmetries in the setting of Algebraic Quantum Field Theory (AQFT). The net of causal loops, previously introduced by the auth…
Causal posets, loops and the construction of nets of local algebras for QFT
Fabio Ciolli, Giuseppe Ruzzi, Ezio Vasselli
We provide a model independent construction of a net of C*-algebras satisfying the Haag-Kastler axioms over any spacetime manifold. Such a net, called the net of causal loops, is c…
Massless scalar free Field in 1+1 dimensions, II: Net Cohomology and Completeness of Superselection Sectors
Fabio Ciolli
As an application of Roberts' cohomology (net cohomology), we prove the completeness of the DHR sectors of the local observables of the model in the title, detailed in [8]. This re…
Massless scalar free Field in 1+1 dimensions I: Weyl algebras Products and Superselection Sectors
Fabio Ciolli
This is the first of two papers on the superselection sectors of the conformal model in the title, in a time zero formulation. A classification of the sectors of the net of observa…
