Topological spaces form the foundational framework for modern analysis and geometry, characterised by a set equipped with a collection of open subsets satisfying specific axioms. This flexible ...

The Menger property, a renowned covering property in topology, offers a generalisation of σ‑compactness by asserting that for any sequence of open covers, one can select finitely many elements from ...

The topological photonics plays an important role in the fields of fundamental physics and photonic devices. The Kagome model, the Su-Schrieffer-Heeger (SSH) model and the other topological models are ...

At TU Wien, researchers have discovered a state in a quantum material that had previously been considered impossible. The ...

In order: space, space with a black hole in it, space with a theorized topological soliton. Gif: PIERRE HEIDMANN/JOHNS HOPKINS UNIVERSITY A team of physicists mathematically built an exotic object ...
