Continuous Tuning of the Charge-Phase Uncertainty in a Josephson Junction

Irena Padniuk, Xianzhe Zeng, Juan Carlos Cuevas +3

Quantum mechanics constrains conjugate observables from being simultaneously measurable with arbitrary precision. In a Josephson junction, these are the transferred electric charge…

Enhancing the Energy Resolution in Scanning Tunneling Microscopy: from dynamical Coulomb blockade to cavity quantum electrodynamics

Xianzhe Zeng, Janis Siebrecht, Haonan Huang +4

Scanning tunneling microscopy and spectroscopy have become indispensable tools for probing condensed matter at atomic length scales, yet achieving ultimate energy resolution remain…

Josephson tunneling through a Yu-Shiba-Rusinov state: Interplay of -shifts in Josephson current and local superconducting order parameter

Andreas Theiler, Christian R. Ast, Annica M. Black-Schaffer

An impurity hosting a magnetic moment coupled to a conventional -wave superconductor gives rise to so-called Yu-Shiba-Rusinov (YSR) states with energies inside the superconducti…

Temperature dependent energy gap for Yu-Shiba-Rusinov states at the quantum phase transition

Andreas Theiler, Christian R. Ast, Annica M. Black-Schaffer

Motivated by recent experiments, which allow for fine tuning of the effective magnetic interaction between the impurity and the superconductor, we investigate the regime around the…

Roadmap on Nanoscale Magnetic Resonance Imaging

Raffi Budakian, Amit Finkler, Alexander Eichler +22

The field of nanoscale magnetic resonance imaging (NanoMRI) was started 30 years ago. It was motivated by the desire to image single molecules and molecular assemblies, such as pro…
