Dirac matters provide a platform for exploring the interplay of their carriers with other quantum phenomena. SrMnSb 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 SrMnSb, 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 SrMnSb, 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.

The decay of a = 8 isomer in Pu and the collective band structure populating the isomer are studied using deep inelastic excitations with Ti and Pb beams, respectively. Precise measurements of branching ratios in the band confirm a clean 9/27/2 for the isomer, validating the systematics of K = 8 two-quasineutron isomers observed in even-, = 150 isotones. These isomers around the deformed shell gap at = 152 provide critical benchmarks for theoretical predictions of single-particle energies in this gateway region to superheavy nuclei.

We present polarization measurement of a Ni-like Ag X-ray laser working in the transient collisional excitation scheme. A calibrated membrane multilayer beam splitter was used to determine the energies of two mutually perpendicular polarization components (s and p components). As a result, we observed a high degree of polarization that fluctuated from shot to shot. The dominant polarization component switched from s to p when pumping was made stronger. The measurement results are discussed from the point of view of the general polarization theory and supported by a numerical simulation based on Maxwell-Bloch equations.

A global plasma turbulence simulation code, ORB5, is presented. A particular feature is the use of straight-field-line magnetic coordinates and a field-aligned Fourier filtering technique that dramatically improves the performance of the code in terms of both the numerical noise reduction and the maximum time step allowed. Another feature is the capability to treat arbitrary axisymmetric ideal MHD equilibrium configurations. The code is validated against an analytical theory of zonal flows and against other codes for a selection of linear and nonlinear tests.
