We show that if $G$ is an amenable group and $A\subseteq G$ has positive upper Banach density, then there is an identity neighborhood $B$ in the Bohr topology on $G$ that is almost contained in $AA^{-1}$ in the sense that $B\backslash AA^{-1}$ has up

In twisted bilayer semiconductors with arbitrary twisting angles, a chiral excitonic system can arise from the interlayer electron-hole Coulomb exchange interaction (F\"{o}rster coupling) that hybridizes the anisotropic intralayer excitons from indiv

In this note we study the natural question of when the generalised F{\o}lner sets exhibiting property A can be chosen to be subsets of the space itself. We show that for many property A spaces $X$, this is indeed possible. Specifically this holds: fo

We demonstrate single-shot and \textit{in situ} absorption imaging of individual Rydberg superatoms. This level of resolution is achieved using an electromagnetically induced transparency scheme involving a Rydberg energy level that is highly sensiti

A new species of Harmonicon F. O. Pickard-Cambridge, 1896, is described from the Cerrado biome in Central-West Brazil, representing the first non-Amazonian and the southernmost record for the genus. Furthermore, we present a new diagnosis of the genu

This work puts forth a new optimal design formulation for planar elastic membranes. The goal is to minimize the membrane's compliance through choosing the material distribution described by a positive Radon measure. The deformation of the membrane it

Hybrid van der Waals heterostructures of organic semiconductors and transition metal dichalcogenides (TMDs) are promising candidates for various optoelectronic devices, such as solar cells and biosensors. Energy-transfer processes in these materials
