Fig. presents the PICI generated from coupling a LiF molecule with an optical cavity. For a nuclear wavepacket that is initially uniformly distributed in θ (Fig. (iii)) which corresponds to a rotational state with a quantum number J = 0, passing through the PICI from the left will cause half of the density to encircle the CI clockwise and the other half, counterclockwise. This causes the two halves to gain phases with opposite signs, causing interference effects when the wavepacket branches meet after the PICI point. These interference effects can be seen in the patterns of the probability density (Fig. (iii)) where, notably, a node at θ = π/2 appears after encirclement due to destructive interference from the Berry phase. Considering a different initial nuclear distribution with a rotational state J = 1 (Fig. (iv)) where the probability density has a much larger amplitude at the parallel (θ = 0) and antiparallel (θ = π) angles of the light-matter coupling, the probability density after encirclement has a lack of a node at θ = π/2 due to constructive interference of the Berry phase. These particular interference features are not consistently present if the Berry phase is removed from the dynamics or if the molecule is prevented from rotating. The presence of the Berry phase is thus an important feature of photochemical simulations involving conical intersections, and can also be experimentally observed when measuring the photo-fragment angular distribution (PAD) in a recent work of the light-induced conical intersection for a H + 2 molecule coupled to an intense laser field. It is thus possible to experimentally test the effect of PICI by measuring the PAD, which is computed in Ref. 95.
