A new study conducted by an international team of researchers has uncovered a global symmetry in topological boundary states. The study, published in the journal Nature Communications, provides insight into the nature of these states and could lead to the development of new technologies such as quantum computers.

The study focused on the behavior of topological boundary states, which form when two-dimensional materials like graphene are brought to the brink of a topological phase transition. These states are of great interest to scientists due to their unique properties. In particular, they are believed to be immune to perturbations, making them ideal for use in quantum computing.

The researchers found that these states have a global symmetry, meaning that they are the same everywhere in the system. This symmetry is particularly interesting because it is present even when the boundary states appear to be chaotic. The discovery of this global symmetry could lead to new ways of understanding and manipulating topological boundary states, which could ultimately lead to the development of new technologies.
