Quantum transport simulations for the next decade: Exploiting quantum topology in emerging 2D-devices

Two-dimensional (2D)- materials will form the basis of future nano-transistors. At the same time, a whole class of 2D-materials are topological insulators - quantum materials which have been at the forefront of condensed matter physics research. They offer symmetry protected ballistic channels that are robust to a large degree against “symmetry permitting” disorder. Furthermore, quantum phase transitions between a conducting topological phase and an insulating trivial phase can be engineered via electrical and magnetic means. These two aspects that innately stem from quantum topology concepts can potentially offer unprecedented possibilities for modern emerging devices [1], thereby paving the way for “topological electronics”.
