Fractional quantum states far from equilibrium could lead to new topology
Topologically protected states of matter enjoy a spotlight in condensed matter physics, bridging abstract geometrical notions from mathematics with materials science to seek new ways of building a future generation of electronics. Topological systems constitute pioneering candidates for the job with unprecedented resilience to external perturbations and novel quantum coherence times. Condensed matter such as ultracold quantum gases can exhibit strongly correlated phenomena such as the fractional quantum Hall effect, in which novel ground states of fractional rather than whole quantum numbers emerge. The topological effect is extremely robust and could be a candidate for fault-tolerant quantum computation, a holy grail in future technologies. The EU-funded NonequilibriumAnyons project is conducting theoretical investigations to study the largely unknown out-of-equilibrium response of strongly correlated systems.
