Founding Source : EUCENTRAL: CENTER FOR QUANTUM TECHNOLOGIES MODELLING - [HORIZON-WIDERA-2023-TALENTS-01-01] — [ERA Chair] project financed by the European Commission (agreement no.: 101186579). Project website: https://eucentral.cft.edu.pl/ About us The Center for Theoretical Physics of the Polish Academy of Sciences (CTP PAS) is a research institute focused on the study of theoretical physics. The CTP is located in Warsaw, Poland, and was founded in 1980. The CTP PAS conducts research in various fields of physics, including quantum information, space and gravity research, semiconductors, and atomic gases. The Institute's strategy is to employ the strongest scientists, giving them the freedom to conduct their research. This has resulted in the CTP's high standing in Poland, world-class publications (in Nature and Science), a large number of grants (approximately 30 projects), and participation in international consortia. In terms of citations per researcher, CTP PAS ranks among the leading institutions in Polish physics. The CTP PAS also hosts a number of scientific events, including seminars, workshops, and conferences, which are open to the public. The Institute also creates educational content accessible on its official YouTube channel. About the role We are seeking two research assistants - PhD students (f/m/x), who will join the Modelling Center for Quantum Technologies group at the CTP PAS, led by Dr. Federico Balducci (Team Leader). The group will collaborate closely with the group of prof. Marzena Szymańska (ERA Chair Holder) at University College London. The candidates (2 half-time positions) will work on numerical methods for quantum open many-body systems related to the project, such as the quantum trajectory method for multimode ultracold gas with particle losses. These methods are already being developed at CTP PAS, but they are not broadly accessible yet, and need to be integrated with other repositories. Enquiries regarding the role or the recruitment process can be addressed to Dr. Federico Balducci ( fbalducci@cft.edu.pl ) and prof. Marzena Szymańska ( mszymanska@cft.edu.pl ).
