Chiral Coupling to Magnetodipolar Radiation

Decoherence through Coupling to the Radiation Field

We consider a quantum particle in a coherent superposition of two well localized wave packets. Through an external harmonic potential the two wave packets are accelerated towards each other, start to overlap, and an interference pattern emerges. When the particle is coupled to the radiation eld, assumed to be in a thermal state, the interference pattern is partially suppressed, which deenes the...

Strong Coupling Qed Breaks Chiral Symmetry

We show that the strong coupling limit of d-dimensional quantum electrodynamics with 2/2 flavors of fermions can be mapped onto the s=1/2 quantum Heisenberg antiferromagnet in d-1 space dimensions. The staggered Néel order parameter is the expectation value of a mass operator in QED and the spin-waves are pions. We speculate that the chiral symmetry breaking phase transition corresponds to a tr...

Strong-coupling expansion of chiral models.

The strong-coupling character expansion of lattice models is reanalyzed in the perspective of its complete algorithmization. The geometric problem of identifying, counting, and grouping together all possible contributions is disentangled from the group-theoretical problem of weighting them properly. The first problem is completely solved for all spin models admitting a characterlike expansion a...

The φNN coupling from chiral loops

Starting from effective Lagrangians which combine a gauge formulation of Vector Meson Dominance with Chiral Lagrangians, the coupling of the φ to the nucleon, which is zero at tree level due to the OZI rule, is calculated perturbatively considering loop contributions to the electric and magnetic form factors. We obtain reasonably smaller values for both form factors than those for ρN N and cons...
