The local structural changes and vibrational characteristics of the (001) surface of an fcc metal in the presence of vacancy/adatom point defects have been studied theoretically. The effect of the size of the vacancy defect and the position of the ad

In the novel stoichiometric iron-based material RbEuFe4As4 superconductivity coexists with a peculiar long-range magnetic order of Eu 4f states; their coexistance is puzzling and represents a challenge for both experiment and theory. Using angle-reso

Using density functional theory, we propose the (MnSb2Te4)·(Sb2Te3)n family of stoichiometric van der Waals compounds that harbor multiple topologically nontrivial magnetic phases. In the ground state, the first three members of the family (n = 0, 1

The electronic energy-band structure of the PrBaCo2O5 + δ cobaltite at the oxygen content close to 5.5 are calculated by the first-principle PAW methods. The semiconductor–metal phase transition at 5 + δ = 5.5 is shown to be a result of the trans

In pnictide RbEuFe4As4, superconductivity sets in at 36 K and coexists, below 15-19 K, with the long-range magnetic ordering of Eu 4f spins. Here we report scanning tunneling experiments performed on cold-cleaved single crystals of the compound. The

The Jahn–Teller effect is a geometrical distortion which lowers the system symmetry and lifts orbital degeneracy in molecules and solids. It affects a wide range of properties, including magnetic and band structures. In this work we propose a famil

We present a theoretical investigation of electron states hosted by magnetic domain walls on the three-dimensional topological insulator surface. The consideration includes the domain walls with distinct vectorial and spatial textures. The study is c

Inelastic interactions of quantum systems with the environment usually wash coherent effects out. In the case of Friedel oscillations, the presence of disorder leads to a fast decay of the oscillation amplitude. Here we show both experimentally and t

Mechanisms of atomic layer-by-layer formation of the equilibrium structure of multilayer Na film on the Cu(001) surface have been studied taking into account relaxation and dynamic (phonon) processes. It has been shown that the atomic rearrangement o

The anisotropy of the quasiparticle lifetime in the layered tungsten dichalcogenide WSe is studied for energies up to 90 eV above the Fermi level. The inverse lifetime is calculated within the GW approximation based on a full energy and momentum depe
