The proposed project aims to establish tight collaborations between the Paul Scherrer Institute (PSI) of Switzerland and Tsinghua University, China, in research on novel quantum materials using advanced laboratory-based techniques and large facilities, such as synchrotron light sources. We will also create a platform for institutional partnership for the on-going scientific activities, as well as for long-term collaborations. We shall exchange postdoctoral fellows and/or doctoral students in joint supervision for research and training in the fields of material sciences and condensed matter physics. With three concrete examples of scientific cases, we shall search for and comprehensively study the forefront themes in materials science and condensed matter physics:1)magnetic Weyl semi-metals and their related quantum anomalous Hall effect materials,2)new 2D high-temperature superconductors, and3)novel topological superconductors.The ultimate and intermediate results in realizing these quantum materials will be of high impact in fundamental science and have great potential for applications, such as novel functional devices and quantum information. Research on novel quantum materials is fast developing worldwide, so that the proposed activities could be adjusted depending on new developments in the field, and the discovery of new materials which are relevant to the line of research in this proposal.Tsinghua University is one of the top universities in China and its Physics Department is one of leading centers in the world in the field of topological quantum materials research and low-dimensional high-temperature superconductors, including experimental discoveries of quantum anomalous Hall effect and single-layer high-temperature superconductivity. The strength of Tsinghua University in materials synthesis and developing advanced laboratory-based equipment will bring benefits to PSI in its research programs on material sciences, and in particular to build up the ensemble of molecular beam epitaxy (MBE) and synchrotron-based angle-resolved photoemission spectroscopy (ARPES) in the near future,PSI, embedded in the ETH Domain alongside ETH and EPFL, with large facilities such as the Swiss Light Source (SLS), the Swiss Free Electron Laser (SwissFEL) and the Swiss Spallation Neutron Source (SINQ), provides great opportunities to domestic universities and the international scientific community for successful achievements in materials science and other disciplines. The high scientific throughput is widely recognized by the international scientific community. Leading expert scientists familiar with the large facilities have performed numerous breakthrough works in their in-house research, including in the fields of material sciences and condensed matter physics. Experiments exploiting large facilities at PSI would be highly beneficial to Tsinghua University in enhancing its materials research programs.
