Supercurrent in BiTe Topological Material-Based Three-Terminal Junctions
Jonas Kölzer, Abdur Rehman Jalil, Daniel Rosenbach +6
In an in-situ prepared three-terminal Josephson junction based on the topological insulator BiTe and the superconductor Nb the transport properties are studied. The differe…
Radiation statistics of a degenerate parametric oscillator at threshold
Fabian Hassler, Steven Kim, Lisa Arndt
As a function of the driving strength, a degenerate parametric oscillator exhibits an instability at which spontaneous oscillations occur. Close to threshold, both the nonlinearity…
Period tripling due to Josephson parametric down-conversion beyond the rotating-wave approximation
Lisa Arndt, Fabian Hassler
Parametrically driven oscillators can display period-tripling in response to a drive at thrice the resonance frequency. In contrast to the parametric instability for period doublin…
Period tripling due to parametric down-conversion in circuit QED
Lisa Arndt, Fabian Hassler
Discrete time-translation symmetry breaking can be observed in periodically-driven systems oscillating at a fraction of the frequency of the driving force. However, with the except…
Universality of photon counting below a bifurcation threshold
Lisa Arndt, Fabian Hassler
At a bifurcation point, a small change of a parameter causes a qualitative change in the system. Quantum fluctuations wash out this abrupt transition and enable the emission of qua…
Statistics of radiation due to non-degenerate Josephson parametric down conversion
Lisa Arndt, Fabian Hassler
In a process called parametric down-conversion, a dc-biased Josephson junction coupled to two microwave resonators emits photon pairs when the Josephson frequency matches the sum o…
Dual Shapiro steps of a phase-slip junction in the presence of a parasitic capacitance
Lisa Arndt, Ananda Roy, Fabian Hassler
Bloch oscillations in a single Josephson junction in the phase-slip regime relate current to frequency. They can be measured by applying a periodic drive to a DC-biased, small Jose…
