A product formula and combinatorial field theory
A. Horzela, P. Blasiak, G. H. E. Duchamp +2
We treat the problem of normally ordering expressions involving the standard boson operators a, a* where [a,a*]=1. We show that a simple product formula for formal power series - e…
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…
Angular Momentum of Photons Emitted by Atoms
M. A. Can, Ozgur Cakir, A. Horzela +3
It is shown that the spin and orbital angular momentum of electric dipole photons have the same operator structure and may differ from each other only by spatial dependence in the…
