WebI'm wondering why the weak interaction only affects left-handed particles (and right-handed antiparticles). Before someone says "because thats just the way nature is" :-), let me explain what I find needs an explanation: In the limit of massless fermions, chirality (handedness) becomes helicity $(\vec S \cdot \hat p)$. WebA vast majority of widely used molecular systems exhibit extremely weak chirality factors ξ ≪ 1, rendering it challenging to separate left- and right-handed enantiomers to high fidelity. Chiral polaritonics can serve this purpose as the collective interaction results in a N scaling of the coupling strength, thus increasing the selectivity.
