A topological group is a group that is also a topological space, where the group operations (multiplication and inversion) are continuous. Metric spaces, on the other hand, are sets equipped with ...

Our research group fabricates and studies colloidal particles with different numbers of handles and genus g. When introduced into a nematic liquid crystal, these particles induce three-dimensional ...

Defects are responsible for many well-known processes: plastic deformations and fracture in metals are governed by dislocations, vortices in the atmosphere show up as tornadoes, disclinations in ...

A team of researchers at ETH led by Tilman Esslinger has now managed to detect topological effects in an artificial solid, in which the interactions can be switched on or off using magnetic fields.

The discovery of topological electronic crystals in twisted graphene offers insights into electron dynamics, with potential implications for quantum computing.
