Chiral phononic and electronic edge modes of EuPtSi

Issam Mahraj, Andrzej Ptok

Systems with P2 $_{1}$ 3 symmetry are characterized by the realization of chiral edge modes, propagating in one direction along closed loops around some high symmetry points of the B…

Phonon Weyl points and chiral edge modes with unconventional Fermi arcs in NbSi $_{2}$

Issam Mahraj, Andrzej Ptok

NbSi $_{2}$ crystallizes in the P6 $_{2}$ 22 symmetry, featuring chiral chains of Si atoms. The absence of inversion symmetry, combined with its chiral structure, gives arise to uniqu…

Theoretical investigation of the photovoltaic properties of MgSnN $_{2}$ for multi-junction solar cells

Issam Mahraj, Mossab Oublal, Andrzej Ptok

The orthorhombic crystal structure of the MgSnN $_{2}$ compound with Pna2 $_{1}$ symmetry has been investigated as a low-cost, non-toxic material for photovoltaic (PV) applications using…

Topological character of the antiferromagnetic EuMg $_{2}$ Bi $_{2}$

Mazharul Islam Mondal, Issam Mahraj, Milo Sprague +8

Antiferromagnetic EuM $_{2}$ Pn $_{2}$ compounds, where M is a metal element and Pn is a pnictogen element, have been recognized as candidates for realizing a topologically nontrivial…
