WSi weak link element with a non-sinusoidal current-phase relation

Sarah C. Jones, Trevyn F. Q. Larson, Sai Pavan Chitta, Heli Vora et autres

Nonlinearity is an essential ingredient for encoding quantum states with non-uniform energy spacing, implementing coherent quantum gates, reading out qubits, amplifying, and mixing electromagnetic signals. In this work, we demonstrate the nonlinear behavior of a constriction fabricated from an amorphous, high-kinetic inductance …

Localized quasiparticles in a fluxonium with quasi-two-dimensional amorphous kinetic inductors

Trevyn F. Q. Larson, Sarah C. Jones, Tamás Kalmár, Sai Pavan Chitta et autres

Disordered superconducting materials with high kinetic inductance are an important resource for generating nonlinearity in quantum circuits and creating high-impedance environments. In thin films fabricated from these materials, the combination of disorder and low effective dimensionality leads to increased order parameter fluctuations …

Symplectic Geometry and Circuit Quantization

Andrew Osborne, Trevyn F. Q. Larson, Sarah C. Jones, Raymond W. Simmonds et autres

Circuit quantization is an extraordinarily successful theory that describes the behavior of quantum circuits with high precision. The most widely used approach of circuit quantization relies on introducing a classical Lagrangian whose degrees of freedom are either magnetic fluxes or electric charges …

The German “Hans-Ertel-Centre for Weather Research” (HErZ)

Sarah C. Jones, Mathias Walter Rotach, Clemens Simmer, Gerhard Adrian et autres

Fundamental research addressing the challenges of weather forecasts and climate monitoring is required in order to steadily improve the quality of meteorological and climatological services. However, the potential of transferring results from this research into operations increases significantly if carried out in …

Designing high-performance superconductors with nanoparticle inclusions: Comparisons to strong pinning theory

Sarah C. Jones, Masashi Miura, Ryuji Yoshida, Takeharu Kato et autres

One of the most promising routes for achieving high critical currents in superconductors is to incorporate dispersed, non-superconducting nanoparticles to control the dissipative motion of vortices. However, these inclusions reduce the overall superconducting volume and can strain the interlaying superconducting matrix, which …

Review of International Experience of Community, Communal and Municipal Ownership of Land

Rob McMorran, Jayne H. Glass, Jane Atterton, Sarah C. Jones et autres

Community landownership in Scotland is generally understood as ownership of title to land and/or assets by a community body, linked to a defined geographic community. It is a relatively distinct category of landownership, regarded as different to public ownership of land (e.g. …
