- Abstract: Topology in general but also topological objects such as monopoles are a
central concept in physics. They are prime examples for the intriguing physics
of gauge theories and topological states of matter. Vector monopoles are
already frequently discussed such as the well-established Dirac monopole in
three dimensions. Less known are tensor monopoles giving rise to tensor gauge
fields. Here we report that tensor monopoles can potentially be realized in
superconducting multi-terminal systems using the phase differences between
superconductors as synthetic dimensions. In a first proposal we suggest a
circuit of superconducting islands featuring charge states to realize a tensor
monopole. As a second example we propose a triple dot system coupled to
multiple superconductors that also gives rise to such a topological structure.
All proposals can be implemented with current experimental means and the
monopole readily be detected by measuring the quantum geometry.

We demonstrate the failure of the Dirac-Bergmann theory for the quantization of realistic, nearly singular superconducting circuits.
The correct treatment of nearly singular systems involves a perturbative Born-Oppenheimer analysis.
We find that the singular limit of this regularized analysis is, in many cases, completely unlike the singular theory.

We show that the electrical conductance and the Wiedemann-Franz ratio of the device at the topological transition have universal values at very low temperatures.
