Nonequilibrium chiral active systems exhibit diverse collective phenomena arising from the interplay between driving forces and interparticle interactions. We numerically investigate a two-dimensional system of particles with competing long-range repulsion and short-range attraction, driven by nonconservative odd forces. We identify five distinct nonequilibrium phases: a crystalline state with long-range translational and orientational order; a triangular velocity configuration exhibiting velocity-space ordering; a nematic phase featuring orientational alignment without polar order; a bubble phase with vortical flows along void boundaries; and a rotating cluster phase showing dynamic restructuring. The transitions between these phases are systematically controlled by varying the attraction strength and the odd-force intensity, revealing a rich phase diagram. Our results underscore the crucial role of odd forces in steering the structural and dynamical evolution of active matter with competing interactions.

02:58Crystal 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.

02:46Crystal 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,...
