Substrate insulated Josephson junctions for superconducting quantum circuits
U. Strobel, L. Radtke, L. Kamps +7
We have developed a fabrication technique for Josephson junctions that employs a three-dimensional patterned, low-loss substrate instead of commonly used organic resists. The techn…
Fast proton transport and neutron production in proton therapy using Fourier neural operators
Francesco Blangiardi, Hunter N. Ratliff, Fabian Teichert +3
Objective: Real-time adaptive proton range verification systems based on produced neutrons require accurate information on their non-isotropic momentum distributions within short t…

Wei Wei, Florian Fuchs, Andreas Zienert +2
Oxygen vacancies are critical for determining the electrochemical performance of fast oxygen ion conductors. The perovskite LaSrCoO, known for its excellent mix…
Quantum transport in graphene nanoribbon networks: complexity reduction by a network decimation algorithm
Tom Simon Rodemund, Fabian Teichert, Martina Hentschel +1
We study electronic quantum transport in graphene nanoribbon (GNR) networks on mesoscopic length scales. We focus on zigzag GNRs and investigate the conductance properties of stati…
Terahertz charge and spin transport in metallic ferromagnets: the role of crystalline and magnetic order
