    Why is polonium simple cubic and so highly anisotropic?

  • Original language description

    Using the state-of-the-art ab initio electronic structure calculations, we explain why $alpha$-Po prefers the simple cubic (s.c.) structure (it is due to the relativistic mass-velocity and Darwin terms), elucidate its extreme elastic anisotropy (this isan intrinsic property of the s.c. crystal structure) and predict a transformation to a mixture of two trigonal structures at pressures of 1-3 GPa.

    Proč má polonium prostou kubickou strukturu a je tak vysoce anizotropické?

  • Czech description

    S použitím moderních metod výpočtů elektronové struktury vysvětlujeme, proč alfa-Po preferuje prostou kubickou strukturu (je to důsledkem relativistického členu "mass-velocity" a Darwinova členu), objasňujeme jeho vysokou elastickou anizotropii (která jeinherentní vlastností prosté kubické struktury) a předpovídáme transformaci alfa-Po na směs dvou trigonálních struktur při tlacích 1-3 GPa.
