Chirality and helicity
WebApr 9, 2024 · The propagating guided modes by optical waveguides hardly produce optical chirality because of the broken symmetry between electric and magnetic components. Here for the first time we discover that the directional coupling of spatially guided modes can create polarization helicity, and thus generate optical spin and chirality. WebOf the utmost importance of chirality in organic compounds and drugs, the present work reports structure-chirality relationship of three steroidal quinoxalines, which were synthesised by condensing diaminobenzenes with cholestenone.

However, a massive particle … Web22 hours ago · The magnetic field and chiral chemical potential evolve with inverse cascading in such a way that the magnetic helicity and chirality cancel each other at all …
WebApr 13, 2014 · Chirality is always Lorentz invariant. Helicity defined h^ = Σ→ ⋅p^, h ^ = Σ → ⋅ p ^, commutes with the Hamiltonian, [h^,H] = 0, [ h ^, H] = 0, but is clearly not Lorentz invariant, because it contains a dot product of a three-momentum. Chirality defined γ5 = iγ0 …γ3, γ 5 = i γ 0 … γ 3, WebWe demonstrate that the helicity-preserving features of our cavities stem from a spin–orbit coupling mechanism seeded inside the cavities by the specific chiroptical features of planar chirality.
