Monometallic complexes based on 3d transition metal ions in certain axial coordination environments can exhibit appreciably enhanced magnetic anisotropy, important for memory applications, due to stabilisation of an unquenched orbital moment. For high-spin trigonal bipyramidal Ni(ii), if competing structural distortions can be minimised, this may result in an axial anisotropy that is at least a...
In the paper, we will focus on relationship between teaching subjects of mathematics and musical art from point view solving non-standard geometric problems. We designed several problems in order to out connection theoretical knowledge practical life. present interdisciplinary relations as one possible innovative forms secondary school.
By introducing a quark source in the nonlinear σ model, we obtain an analytic boost-invariant solution as a candidate for the disoriented chiral condensate (DCC) in 3+1 dimensions. In order to trigger formation of the DCC, a strong transfer of axial isospin charge must occur between the expanding source and the interior in the baked Alaska scenario. An explicit chiral symmetry breaking is incor...
We reexamine the quark mass induced term in chiral Lagrangian in color-flavor locking phase in dense QCD, and show that the meson mass term is determined by three independent invariants under chiral-axial symmetry, and is given in terms of the quark mass, gap, and the chemical potential by mπ ∼ mq∆/μ ln(μ2/∆2). Thus mesons become massless as μ → ∞. Cold, dense quark system with three massless q...
