Ultrasmall CdSe quantum dots (QDs) with diameters up to 2 nm show broad
photoluminescence (PL) spectra presumably due to emission from band-edge excitons and …

We investigate a family of hexagonal 2D covalent organic frameworks (COFs) with phenyl
and biphenyl spacer units and different chemical linker species. Chemical trends are …

The origin of the high-frequency shoulder (HFS) observed above the longitudinal optical
(LO) peak around 230 cm–1 in the Raman spectra of CdSe quantum dots (QDs) has been …

Recently, plasmonic resonances in molecules, clusters, and nanostructures have gathered a
lot of attention for their potential range of applicability. Unlike other metal nanostructures, a …

Supersolids are a phase of matter exhibiting both superfluidity and a periodic density
modulation typical of crystals. When formed via quantum phase transition from a superfluid …

By extending the current understanding and use of magnonics beyond conventional planar
systems, we demonstrate the surface localization of ferromagnetic resonance (FMR) modes …

Recent advancements in the field of topological band theory have significantly contributed to
our understanding of intriguing topological phenomena observed in various classical and …

Bulk-boundary correspondence establishes the connection between the topological
properties of the bulk and the edge states when a boundary is present. However, the …

Two-dimensional higher-order topology is usually studied in (nearly) particle-hole symmetric
models, so that an edge gap can be opened within the bulk one. But more often the edge …

Multifractality of quantum states plays an important role for understanding numerous
complex phenomena observed in different branches of physics. The multifractal properties of …
