On clean, weakly clean, and feebly clean commutative group rings
Yuanlin Li, Qinghai Zhong
A ring is said to be clean if each element of can be written as the sum of a unit and an idempotent. is said to be weakly clean if each element of is either a sum o…
Kelvin's Chirality of Optical Beams
Sergey Nechayev, Jörg S. Eismann, Rasoul Alaee +3
Geometrical chirality is a property of objects that describes three-dimensional mirror-symmetry violation and therefore it requires a non-vanishing spatial extent. In contrary, opt…
Topological transitions to Weyl states in bulk BiSe: Effect of hydrostatic pressure and doping
Sudip Kumar Saha, Hrishit Banerjee, Manoranjan Kumar
BiSe, a layered three dimensional (3D) material, exhibits topological insulating properties due to presence of surface states and a band gap of 0.3 eV in the bulk. We study…
Molecular anchoring stabilizes low valence Ni(I)TPP on copper against thermally induced chemical changes
Henning Maximilian Sturmeit, Iulia Cojocariu, Matteo Jugovac +14
Many applications of molecular layers deposited on metal surfaces, ranging from single-atom catalysis to on-surface magnetochemistry and biosensing, rely on the use of thermal cycl…
Signatures of an Atomic Crystal in the Band Structure of a Molecular Thin Film
Norman Haag, Daniel Lüftner, Johannes Seidel +8
Transport phenomena in molecular materials are intrinsically linked to the orbital character and the degree of localization of the valence states. Here, we combine angle-resolved p…
High-Temperature Conventional Superconductivity in the Boron-Carbon system: Material Trends
Santanu Saha, Simone Di Cataldo, Maximilian Amsler +23
In this work we probe the possibility of high-temperature conventional superconductivity in the boron-carbon system, using ab-initio screening. A database of 320 metastable structu…
