Tunable skyrmion bag textures in surface phonon polariton lattices
Abstract:
The image shows an artistic depiction of the out-of-plane electric field component of a moiré skyrmion superlattice. This lattice harbors skyrmion bags as complex multi-skyrmion topological excitations. The field distribution is obtained by interfering surface phonon polariton waves on a silicon carbide membrane. On this platform, the topological character of the skyrmion bags can be tuned between bubble- and Néel-type, due to the fully accessible sublinear dispersion of the surface phonon polaritons. More details can be found in the Research Article by Julian Schwab and co-workers (DOI: 10.1002/nap2.70015).

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
Fermi Level Dynamics
Electron affinity in semiconductors refers to the energy gap between the minimum of its conduction band and the vacuum level and it is a critical parameter in determining how easily a semiconductor can accept additional electrons.
