2010/11/23
Random processes characterized by density probabilities with a long tail–L´evy-type
processes– have been found in very different phenomena and fields such as biology, economy, and physics.
Full electrical control of Charge and Spin conductance through Interferometry of Edge States in Topological Insulators
Full electrical control of Charge Spin conductance Topological Insulators

We investigate electron interferometry of edge states in Topological Insulators. We show that,
when inter-boundary coupling is induced at two quantum point contacts of a four terminal setup,
both Fa...
