RhPb was initially recognized as one of CoSn-like compounds with P6/mmm symmetry, containing an ideal kagome lattice of d-block atoms. However, theoretical calculations predict the realization of the phonon soft mode, which leads to the kagome lattic

Substantial acceleration of research and more efficient utilization of resources can be achieved in modelling investigated phenomena by identifying the limits of system's accessible states instead of tracing the trajectory of its evolution. The propo

The DFT molecular dynamics modelling of the melting process confirmed high structural instability of the Fe-terminated nanoparticles and a strong stabilizing effect of the Pt-termination in the FePt shell-type icosahedral particles.

The lattice vibrational properties of $\alpha-Sn$ (gray tin) were investigated experimentally by temperature-dependent x-ray diffraction and theoretically by density functional theory calculations. Similar to the other elements of group IV, $\alpha-S

Using the density functional theory, we study the structural and lattice dynamical properties of europium sesquioxide ($Eu_{2}O_{3}$) in the cubic, trigonal, and monoclinic phases. The obtained lattice parameters and energies of the Raman modes show

Computational investigation of anharmonic and temperature-dependent aspects of lattice dynamics requires, among other things, replication of the conditions of thermal equilibrium. [...]

The recently discovered heavy fermion ${\mathrm{CeRh}}_{2}{\mathrm{As}}_{2}$ compound crystallizes in nonsymmorphic $P4/nmm$ symmetry, which enables the occurrence of topological protection. Experimental results show that this material exhibits unusu
