Arrow of time and quantum physics
Detlev Buchholz, Klaus Fredenhagen
Based on the hypothesis that the (non-reversible) arrow of time is intrinsic in any system, no matter how small, the consequences are discussed. Within the framework of local quant…
Algebraic quantum field theory: objectives, methods, and results
Detlev Buchholz, Klaus Fredenhagen
Algebraic quantum field theory is a general mathematical framework for relativistic quantum physics, based on the theory of operator algebras. It comprises all observable and opera…
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…
Causal Lie products of free fields and the emergence of quantum field theory
Detlev Buchholz, Roberto Longo, Karl-Henning Rehren
All causal Lie products of solutions of the Klein-Gordon equation and the wave equation in Minkowski space are determined. The results shed light on the origin of the algebraic str…
Proper condensates and off-diagonal long range order
Detlev Buchholz
Within the framework of the algebra of canonical commutation relations in Euclidean space, a long range order between particles in bounded regions is established in states with a s…
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…
