Current circulation in triangle quantum-dot metastructures

arXiv:1802.02121 (LA-UR-18-20615)
In this work, we study transport in a simple triangle quantum-dot metastructures. By modeling the systems as open quantum systems, circulating current is found without external magnetic field/vector potential. The same finding is also discovered in isolated systems. The models and results can be tested in proposed experiments. This study reveals interesting transport phenomenon in non-trivial topology and geometry of the quantum systems.
