Measuring Zak phase in room-temperature atoms

In topological insulators, global geometric phases of energy bands determine the existence of unidirectionally propagating edge states, which are immune to local defects, bringing a new stage for designing noise-resilient ...

Topological phase detected in spin chains

In some materials, there are phases between which a transition is not possible because they are protected by a certain form of symmetry. Physicists refer to these as topological phases. One example of this is the Haldane ...

Topological phases in biological systems

LMU physicists have shown that topological phases could exist in biology, and in so doing they have identified a link between solid-state physics and biophysics.
