Materials with topologically protected conducting or superconducting surface states are predicted to exhibit many unusual phenomena.
These phenomena include:
- dissipationless transport along the edges of 2D structures
- quantized anomalous hall conductance and inverse spin galvanic effect
- exotic signatures of fundamental phenomena such as the Witten effect, wormholes and image magnetic monopoles
- ability to host Majorana fermions, a new type of electronic particle that uniquely retains a quantum mechanical memory of its history – a property unlike any known today.
SBQMI researchers are discovering how to exploit these phenomena to:
- transform graphene into a 2D topological insulator,
- understand the connection between bulk properties and the protected surface state in 3D topological material and which may form topological insulators
- launch a new effort to investigate Marjorana fermions in networks of semi-conductor quantum wires.
