Quantum Transport Enhancement by Time-Reversal Symmetry Breaking

Quantum mechanics still provides new unexpected effects when considering the transport of energy and information. Models of continuous time quantum walks, which implicitly use time-reversal symmetric Hamiltonians, have been intensely used to investigate the effectiveness of transport. Here it will be shown how breaking time-reversal symmetry in this model can enable directional control, enhancement, and suppression of quantum transport. Examples ranging from exciton transport to complex networks will be presented. This opens new prospects for more efficient methods to transport energy and information.
