Noncollinear electric dipoles in a polar, chiral phase of CsSnBr perovskite
Douglas H. Fabini, Kedar Honasoge, Adi Cohen +12
Polar and chiral crystal symmetries confer a variety of potentially useful functionalities upon solids by coupling otherwise noninteracting mechanical, electronic, optical, and mag…
Disentangling the Effects of Structure and Lone-Pair Electrons in the Lattice Dynamics of Halide Perovskites
Sebastián Caicedo-Dávila, Adi Cohen, Silvia G. Motti +8
Metal halide perovskites have shown great performance as solar energy materials, but their outstanding optoelectronic properties are paired with unusually strong anharmonic effects…
Symmetry-enforced topological band crossings in orthorhombic crystals: Classification and materials discovery
Andreas Leonhardt, Moritz M. Hirschmann, Niclas Heinsdorf +3
We identify all symmetry-enforced band crossings in nonmagnetic orthorhombic crystals with and without spin-orbit coupling and discuss their topological properties. We find that or…
Symmetry-enforced band crossings in tetragonal materials: Dirac and Weyl degeneracies on points, lines, and planes
Moritz M. Hirschmann, Andreas Leonhardt, Berkay Kilic +2
We study the occurrence of symmetry-enforced topological band crossings in tetragonal crystals with strong spin-orbit coupling. By computing the momentum dependence of the symmetry…
