WebIn the first section, we explore the topics of chirality and helicity. Chirality is an inherent property of particles, whereas helicity of a particle depends on the particle’s momentum. … WebBased on numerical simulations of a gold and silicon nanosphere, it is discussed how metallic and dielectric nanostructures can generate chiral electromagnetic fields upon interaction with chiral light, offering guidelines for the rational design of nanostructure-enhanced electromagnetic chirality.
Web22 hours ago · We study the evolution of magnetic fields coupled with chiral fermion asymmetry in the framework of chiral magnetohydrodynamics with zero initial total chirality. The initial magnetic field has a turbulent spectrum peaking at a certain characteristic scale and is fully helical with positive helicity.
