Stability of B2 compounds: Role of the $M$ point phonons

Although many binary compounds have the B2 (CsCl-type) structure in the thermodynamic phase diagram, an origin of the structural stability is not understood well. Here, we focus on 416 compounds in the B2 structure extracted from the Materials Projec

Lattice stability of ordered Au-Cu alloys in the warm dense matter regime

Autor: Ono, Shota, Kobayashi, Daigo

Publikováno v: Phys. Rev. B 103, 094114 (2021)

In the warm dense regime, where the electron temperature is increased to the same order of the Fermi temperature, the dynamical stability of elemental metals depends on its electronic band structure as well as its crystal structure. It has been known

Pseudo-Fermi surface and phonon softening in sodium with a stepwise electron distribution

Autor: Ono, Shota, Kobayashi, Daigo

The absorption of light by a metal disturbs the electron distribution around the Fermi surface. Here, we calculate the phonon dispersion relations of free-electron-like metal, bcc sodium, with a stepwise electron distribution function by using a mode
