With the advances of microfabrication techniques in recent years it has become possible to
fabricate tunnel junctions of increasingly smaller dimensions and thereby decreasing …

Single-electronics is a fascinating technology which reveals new physical effects of charge
transport. It has many benefits and great figure of merits but also several open challenges …

Transport through molecular devices with strong coupling to a single vibrational mode is
considered in the case where the vibration is damped by coupling to the environment. We …

We explore the photonic (bright) side of the dynamical Coulomb blockade (DCB) by
measuring the radiation emitted by a dc voltage-biased Josephson junction embedded in a …

The current-voltage characteristics of ultrasmall Josephson junctions sensitively depend on
the electromagnetic environment of the junction. When the charging energy exceeds the …

The tunnelling current in scanning tunnelling spectroscopy (STS) is typically and often
implicitly modelled by a continuous and homogeneous charge flow. If the charging energy of …

Cooling the junction of a scanning tunneling microscope to millikelvin temperatures is
fundamental for high-resolution scanning tunneling spectroscopy. However, accurately …

The Josephson effect provides a direct method to probe the strength of the pairing
interaction in superconductors. By measuring the phase fluctuating Josephson current …

We have embedded a voltage-biased Cooper-pair transistor (CPT) in a high-Q
superconducting microwave cavity. When the energy given to a tunneling Cooper pair by the …

We focus on a recently experimentally realized scenario of normal-metal–insulator–
superconductor tunnel junctions coupled to a superconducting resonator. We develop a first …
