When molecules are coupled to an optical cavity, new light–matter hybrid states, so-called
polaritons, are formed due to quantum light–matter interactions. With the experimental …

By virtue of the well‐developed micro‐and nanofabrication technologies and rapidly
progressing surface functionalization strategies, silicon‐based devices have been widely …

Non-Abelian braiding has attracted substantial attention because of its pivotal role in
describing the exchange behaviour of anyons—candidates for realizing quantum logics. The …

The Möbius strip, a fascinating loop structure with one-sided topology, provides a rich
playground for manipulating the non-trivial topological behaviour of spinning particles, such …

Topology is central to phenomena that arise in a variety of fields, ranging from quantum field
