Catalytic Activation of Bell Nonlocality
Jessica Bavaresco, Nicolas Brunner, Antoine Girardin +2
The correlations of certain entangled states can be perfectly simulated classically via a local model. Hence such states are termed Bell local, as they cannot lead to Bell inequali…
Heisenberg-Weyl algebra revisited: Combinatorics of words and paths
P. Blasiak, A. Horzela, G. H. E. Duchamp +2
The Heisenberg-Weyl algebra, which underlies virtually all physical representations of Quantum Theory, is considered from the combinatorial point of view. We provide a concrete mod…
Hopf Algebra Structure of a Model Quantum Field Theory
A. I. Solomon, G. E. H. Duchamp, P. Blasiak +2
Recent elegant work on the structure of Perturbative Quantum Field Theory (PQFT) has revealed an astonishing interplay between analysis(Riemann Zeta functions), topology (Knot theo…
Partition functions and graphs: A combinatorial approach
Allan I. Solomon, Pawel Blasiak, Gerard Duchamp +2
Although symmetry methods and analysis are a necessary ingredient in every physicist's toolkit, rather less use has been made of combinatorial methods. One exception is in the real…
One-parameter groups and combinatorial physics
Gerard Duchamp, Karol A. Penson, Allan I. Solomon +2
In this communication, we consider the normal ordering of sums of elements of the form (a*^r a a*^s), where a* and a are boson creation and annihilation operators. We discuss the i…
Combinatorial Physics, Normal Order and Model Feynman Graphs
A. I. Solomon, P. Blasiak, G. Duchamp +2
The general normal ordering problem for boson strings is a combinatorial problem. In this note we restrict ourselves to single-mode boson monomials. This problem leads to elegant g…
