Quantum Transport and Correlations

Nanoelectronic devices can display spectacular quantum effects in transport. Electron interactions and correlations between electrons and bosonic degrees of freedom often play a crucial role.

At the INT we work on hybrid materials, where superconducting and (ferro-) magnetic materials are combined to allow the tuning of the interfacial superconducting state on transistors where the controllable movement of a single-atom provides the switching mechanism, on spin-polarized transport through molecules contacted via low temperature STM, on nanowire networks which are dominated by electron interactions, or on engineering of quantum states by combining quantum dots with single electron effects localized photon fields.
