High-symmetry thermoelectric materials usually have the advantage of very high band degeneracy, while low-symmetry thermoelectrics have the advantage of very low lattice thermal conductivity. If the symmetry breaking of band degeneracy is small, both effects may be realized simultaneously. Here we ...
Low-symmetry polymorph of GaP upends bonding paradigms of metallic high-pressure III–V compounds The pressure-induced polymorphism of binary octet compounds has long been considered a settled problem although the possible atomic disordering of some phases remains a puzzling observation. Taking GaP as ...
Here we report the discovery of a family of self-constructing cyclic macromolecules with stable folded conformations of low symmetry, which include some with a prime number (13, 17 and 23) of units, despite being formed from a single component. The formation of these objects amounts to the ...

A new paramagnetic center of orthorhombic symmetry with spin S = 1/2 is revealed in KTaO 3 : Ni crystals. The well-resolved superhyperfine EPR structure consisting of 15 components indicates preferred interaction of the center with two tantalum nuclei ( 181 Ta, I = 7/2). This center does...
In this work, we have explored new stable structures of the Au32Z (Z = +1, 0, −1) clusters. Theoretical calculations using density functional theory within the generalized-gradient approximation were performed. Our results show that, in the anion state (Au32-), low-symmetry (disordered)...
Intricate Low-Symmetry Ag6L4 Capsules Formed by Anion-Templated Self-Assembly of the Stereoisomers of an Unsymmetric Ligand doi:10.1021/jacs.4c11583Metal–organic cages and capsules exhibit space-specific functions based on their discrete hollow structures. To acquire enzyme-like asymmetric or ...

Some of the complications which arise in labelling angular-momentum states in low- symmetry systems are discussed. In particular the assignment of irreducible representation labels for spin-orbit coupled states can be quite tricky because of the existence of automorphisms of the symmetry group of the...
The spin Hall effect (SHE) is usually observed as a bulk effect in high-symmetry crystals with substantial spin–orbit coupling (SOC), where the symmetric spin–orbit field imposes a widely encountered trade-off between spin Hall angle (θSH) and spin di
