Photon chirality
WebApr 5, 2024 · We study the mixing of the QCD/QCD-like axion and light-flavor mesons π0, η, η′ within the framework of U(3) chiral perturbation theory up to next-to-leading order in this work. The axion-meson mixing formulas are calculated order by order in the U(3) δ-expansion scheme, namely the joint expansions of the momentum, light-quark masses … WebJan 15, 2016 · The Weyl semimetal is characterized by three-dimensional linear band touching points called Weyl nodes. These nodes come in pairs with opposite chiralities. We show that the coupling of circularly polarized photons with these chiral electrons generates a Hall conductivity without any applied magnetic field in the plane orthogonal to the light …
