Ab initio calculations of phonon spectra in ATiO3 perovskite crystals (A = Ca, Sr, Ba, Ra, Cd, Zn, Mg, Ge, Sn, Pb)
Alexander I. Lebedev
The phonon spectra of calcium, strontium, barium, radium, cadmium, zinc, magnesium, germanium, tin, and lead titanates with the perovskite structure are calculated from first princ…
Properties of BaTiO3/BaZrO3 ferroelectric superlattices with competing instabilities
Alexander I. Lebedev
Properties of (BaTiO)/(BaZrO) ferroelectric superlattices (SLs) with 1--7 grown in the [001] direction are calculated from first principles within the densi…
The New Milky Way: a wide-field survey of optical transients near the Galactic plane
Kirill Sokolovsky, Stanislav Korotkiy, Alexandr Lebedev
Currently, it may take days for a bright nova outburst to be detected. With the few exceptions, little is known about novae behaviour prior to maximum light. A theoretically-predic…
Crystal structure and properties of barium thorate BaThO from first principles
Alexander I. Lebedev
The phonon spectrum of cubic BaThO with the perovskite structure is calculated from first principles within the density functional theory. The analysis of unstable modes in the…
