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 ...

Topological photonics promises robust light transport immune to disorder, but existing linear systems are essentially static ...

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

Topological photonics has emerged as a powerful paradigm for achieving robust light transport that is immune to imperfections, disorder, and ...
