The solid Earth's inner core (IC) is a sphere with radius of about 1300 km in the center Earth. information IC comes mainly from seismic studies. composition obtained by matching data and properties candidate phases subjected to high pressure (P) temperature (T). close match between density iron suggests that main constituent iron. However, stable phase still subject debate. One such phase, bod...

The body-centered cubic (BCC) lattice is the optimal three-dimensional sampling lattice. Its optimality stems from the fact that its dual, the face-centered cubic (FCC) lattice, achieves the highest sphere-packing efficiency. In order to approximate a scalar-valued function from samples that reside on a BCC lattice, spline-like compact kernels have been recently proposed. The lattice translates...

Ordinary Coincidence Site Lattices (CSLs) are defined as the intersection of a lattice Γ with a rotated copy RΓ of itself. They are useful for classifying grain boundaries and have been studied extensively since the mid sixties. Recently the interests turned to so-called multiple CSLs, i.e. intersections of n rotated copies of a given lattice Γ, in particular in connection with lattice quantize...

Plasticity of body-centered cubic (bcc) metals is atypical at low temperatures, caused by the important lattice friction 1/2〈111〉 screw dislocations. In this paper, we present a yield criterion that can be used to predict stress and active slip systems in all bcc transition for any applied stress. The fully parametrized on ab initio calculations dislocation glide properties, case uniaxial loadi...
