Pressure-induced topological phases of KNa2Bi
I. Yu. Sklyadneva,Igor P. Rusinov,Igor P. Rusinov,Rolf Heid,Klaus Peter Bohnen,Pedro M. Echenique,Pedro M. Echenique,Pedro M. Echenique,Eugene V. Chulkov,Eugene V. Chulkov,Eugene V. Chulkov +10 more
TL;DR: The calculated phonon dispersions show that KNa2Bi is dynamically stable both in the cubic structure (at any considered pressures) and in the tetragonal phase (under uniaxial strain).
Temperature-driven topological quantum phase transitions in a phase-change material Ge2Sb2Te5
TL;DR: It is demonstrated by predicting from first-principles calculations that stable crystal structures of Ge2Sb2Te5 possess different topological quantum phases: a topological insulator phase is realized in low-temperature structure and Weyl semimetal phase is a characteristic of the high-tem temperature structure.

Resolubility of image-potential resonances
TL;DR: In this article, a theory of image-potential states is presented for the general case where these surface electronic states are resonant with a bulk continuum, and it extends the multiple scattering approach of Echenique and Pendry into the strong coupling regime while retaining independence from specific forms of surface and bulk potentials.

Electron-phonon relaxation and excited electron distribution in gallium nitride
TL;DR: In this article, the authors developed a theory of energy relaxation in semiconductors and insulators highly excited by the long-acting external irradiation and derived the equation for the non-equilibrium distribution function of excited electrons.
