Dirac matters provide a platform for exploring the interplay of their carriers with other quantum phenomena. Sr$$_{1-x}$$Mn$$_{1-y}$$Sb$$_{2}$$ has been proposed to be a magnetic Weyl semimetal and provides an excellent platform to study the coupling between Weyl fermions and magnons. We performed inelastic neutron scattering measurements on single crystals of Sr$$_{1-x}$$Mn$$_{1-y}$$Sb$$_{2}$$, and found The dispersion in the magnetic Mn layer extends up to about 76 meV, while that between the layers has a narrow band width of 6 meV. Despite the coexistence of Weyl fermions and magnons, we find no clear evidence that the magnetic dynamics are influenced by the Weyl fermions in Sr$$_{1-x}$$Mn$$_{1-y}$$Sb$$_{2}$$, possibly because that the Weyl fermions and magnons reside in the Sb and Mn layers separately, and the interlayer coupling is weak due to the quasi-two-dimensional nature of the material.

In N$$_2$$O a detailed study of the vibrational distribution of the state reached after decay of core-to-$$pi^*$$ excitation of N terminal, N central and O 1s core levels is reported. We observe a change in the relative intensity of bending versus stretching modes while scanning the photon energy across all three resonances. While this effect is known to be due to the Renner-Teller splitting in the core-excited states, we could derive that the antisymmetric stretching is excited mainly in the decay of the N terminal 1s-to-$$pi^*$$ excitation. An explanation for such selectivity is provided in terms of interplay of vibrational structure on potential energy surfaces of different electronic states involved in the process.
