Electronic and dynamical properties of cobalt monogermanide CoGe phases under pressure
Surajit Basak, Aksel Kobiałka, Małgorzata Sternik +5
We present the pressure dependence of the electronic and dynamical properties of six different CoGe phases: orthorhombic Cmmm, hexagonal P6/mmm and P2m, monoclinic C2/m, c…
Lattice dynamics study of electron-correlation-induced charge density wave in antiferromagnetic kagome metal FeGe
Andrzej Ptok, Surajit Basak, Aksel Kobiałka +5
Electron-correlation-driven phonon soft modes have been recently reported in the antiferromagnetic kagome FeGe compound and associated with the observed charge density wave (CDW).…
Phononic drumhead surface state in distorted kagome compound RhPb
Andrzej Ptok, William R. Meier, Aksel Kobiałka +9
RhPb was initially recognized as one of a CoSn-like compounds with symmetry, containing an ideal kagome lattice of -block atoms. However, theoretical calculations predi…
Pb (=Pd,Pt and =S,Se) with transition metal kagome net: Dynamical properties, phonon nodal line, phonon surface states, and chiral phonons
Surajit Basak, Aksel Kobiałka, Andrzej Ptok
Shandite with NiPbS chemical formula and Rm symmetry, contains the kagome sublattice formed by the transition metal atoms. Recent experimental results co…
Dynamical properties of magnetic topological insulator BiTe (Mn, Fe): phonons dispersion, Raman active modes, and chiral phonons study
Aksel Kobiałka, Małgorzata Sternik, Andrzej Ptok
Recently discovered magnetic topological insulators BiTe (Mn, Fe) crystallize into the rhombohedral structure and exhibit the antiferromagnetic order…
Dynamical Study of the Origin of the Charge Density Wave in VSb (K, Rb, Cs) Compounds
Andrzej Ptok, Aksel Kobiałka, Małgorzata Sternik +4
Systems containing the ideal kagome lattice can exhibit several distinct and novel exotic states of matter. One example of such systems is a recently discovered VSb…
Chiral phonons in honeycomb sublattice of layered CoSn-like compounds
Andrzej Ptok, Aksel Kobiałka, Małgorzata Sternik +5
Hexagonal and kagome lattices exhibit extraordinary electronic properties. It is a natural consequence of additional discrete degree of freedom associated with a valley or the occu…
First principles study of topological phase in chains of transition metals
Aksel Kobiałka, Przemysław Piekarz, Andrzej M. Oleś +1
Recent experiments have shown the signatures of Majorana bound states at the ends of magnetic chains deposited on a superconducting substrate. Here, we employ first principles calc…
