Chiral selection rule
WebFeb 9, 2024 · We examined the chirality dependent optical selection rules in two-dimensional monolayer materials with the honeycomb lattice, and based on symmetry argument, we generalized these rules to multi-photon transitions of arbitrary orders. We also presented the phase relations between incident and outgoing photons in such processes. … WebDec 15, 2024 · The selection rules of the electromagnetic transitions for ChP violation are revealed, and E 2, M 1, and E 3 transitions are found to link the states with different B only. Starting from the yrast and yrare chiral doublets at I 0 for the positive parity and negative parity, the ChP quartet bands are constructed with the E 2 transitions between ...
