Quantum Transport (QT)

The research group works on theoretical problems in quantum transport.

Our group works on theoretical problems in quantum transport. Central research topics include dynamic single-electron emitters, noise and fluctuations in electronic conductors, single-electron tunnelling and interactions, and charge transport in hybrid micro-wave cavity architectures. In related areas, we are also interested in non-classical correlations and entanglement as well as quantum jump trajectories. We employ a range of theoretical tools from scattering theory, quantum many-body physics, and statistical mechanics.
