Here we report the fabrication of gate-defined symmetry-broken Josephson junctions in magic-angle twisted bilayer graphene, where the weak link is gate-tuned close to the correlated insulator state with a moiré filling factor of υ = −2. We observe a phase-shifted and asymmetric Fraunhofer pattern with a pronounced magnetic hysteresis. Our theoretical calculations of the junction weak link—with valley polarization and orbital magnetization—explain most of these unconventional features. The effects persist up to the critical temperature of 3.5 K, with magnetic hysteresis observed below 800 mK. We show how the combination of magnetization and its current-induced magnetization switching allows us to realise a programmable zero-field superconducting diode.

The system is assumed to have quasi-positive non-linearities and to satisfy an entropy inequality. The difficulties in establishing global renormalised solutions caused by possibly degenerate diffusion are overcome by introducing a new class of weighted truncation functions. By means of the obtained global renormalised solutions, we study the large-time behaviour of complex balanced systems arising from chemical reaction network theory with non-linear diffusion. When the reaction network does not admit boundary equilibria, the complex balanced equilibrium is shown, by using the entropy method, to exponentially attract all renormalised solutions in the same compatibility class. This convergence extends even to a range of non-linear diffusion, where global existence is an open problem, yet we are able to show that solutions to approximate systems converge exponentially to equilibrium uniformly in the regularisation parameter.","lang":"eng"}]},{"related_material":{"record":[{"id":"10013","relation":"earlier_version","status":"public"}]},"author":[{"last_name":"Hensel","first_name":"Sebastian","orcid":"0000-0001-7252-8072","id":"4D23B7DA-F248-11E8-B48F-1D18A9856A87","full_name":"Hensel, Sebastian"},{"first_name":"Tim","last_name":"Laux","full_name":"Laux, Tim"}],"volume":25,"date_created":"2023-05-21T22:01:06Z","date_updated":"2023-08-01T14:43:29Z","year":"2023","acknowledgement":"This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement no. 948819), and from the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) under Germany’s Excellence Strategy – EXC-2047/1 – 390685813.","publisher":"EMS Press","department":[{"_id":"JuFi"}],"publication_status":"published","ec_funded":1,"file_date_updated":"2023-05-22T07:24:13Z","doi":"10.4171/IFB/484","language":[{"iso":"eng"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"arxiv":["2108.01733"],"isi":["000975817300002"]},"oa":1,"project":[{"_id":"0aa76401-070f-11eb-9043-b5bb049fa26d","grant_number":"948819","name":"Bridging Scales in Random Materials","call_identifier":"H2020"}],"quality_controlled":"1","isi":1,"publication_identifier":{"issn":["1463-9963"],"eissn":["1463-9971"]},"month":"04","oa_version":"Published Version","file":[{"relation":"main_file","file_id":"13045","checksum":"622422484810441e48f613e968c7e7a4","success":1,"date_created":"2023-05-22T07:24:13Z","date_updated":"2023-05-22T07:24:13Z","access_level":"open_access","file_name":"2023_Interfaces_Hensel.pdf","file_size":867876,"content_type":"application/pdf","creator":"dernst"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"13043","intvolume":" 25","ddc":["510"],"status":"public","title":"Weak-strong uniqueness for the mean curvature flow of double bubbles","issue":"1","abstract":[{"lang":"eng","text":"We derive a weak-strong uniqueness principle for BV solutions to multiphase mean curvature flow of triple line clusters in three dimensions.

Nowadays, it can also be performed via automated machines that weave threads with high spatial accuracy. A characteristic feature of the appearance of the threads is a high degree of anisotropy. The anisotropic behavior is caused by depositing thin but long strings of thread. As a result, the stitched patterns convey both color and direction. Artists leverage this anisotropic behavior to enhance pure color images with textures, illusions of motion, or depth cues. However, designing colorful embroidery patterns with prescribed directionality is a challenging task, one usually requiring an expert designer. In this work, we propose an interactive algorithm that generates machine-fabricable embroidery patterns from multi-chromatic images equipped with user-specified directionality fields.We cast the problem of finding a stitching pattern into vector theory. To find a suitable stitching pattern, we extract sources and sinks from the divergence field of the vector field extracted from the input and use them to trace streamlines. We further optimize the streamlines to guarantee a smooth and connected stitching pattern. The generated patterns approximate the color distribution constrained by the directionality field. To allow for further artistic control, the trade-off between color match and directionality match can be interactively explored via an intuitive slider. We showcase our approach by fabricating several embroidery paths.","lang":"eng"}],"citation":{"ista":"Liu Z, Piovarci M, Hafner C, Charrondiere R, Bickel B. 2023.
