This project focus on the theory and applications for self-assembly of effective forces emerging between passive
and active objects immersed in a binary liquid mixtures close to the critical demixing point. The project is theoretical and computational but will benefit from empirical data and close collaborations with experimental colleagues. The scientific goal of this project is threefold: to build on our expertise in modelling fluctuation-induced forces in equilibrium to firstly, gain insight into temperature controlled assembly of two types of particles into colloidal alloys and, secondly, to elucidate the physical determinants of the formation of lipid and protein domains in membranes. The third goal is to expose the basic physical principles of the interaction of active particles and, furthermore, uncover dynamical consequences of these forces that can range from trapping, scattering and simple or complex orbits. Our well-controlled model systems will provide insight into the fundamentals of non-equilibrium physics.

• Participation in developing concepts and tools to realize one or more aims of the project. Specifically, for the first goal of the project it will be theoretical and numerical determination of the aggregation phenomena for the mixture of two types of colloids differing in size suspended in the binary liquid mixture near its critical point. Based on the obtained theoretical results designing colloidal alloys finely tunable by fluctuation-induced forces. Exploring the impact of nonequilibrium conditions.
• Scientific initiative and contribution through regular reporting and publishing, as well as presenting at group meetings, national and international conferences;
• Providing help and supervision to PhD students.

A full-time position. It is possible to change the starting date in the justified case. 100% of the work time will be devoted to the realisation of the project. No teaching obligations. We offer work in the scientifically stimulating, friendly environment in a dynamic, motivated and ready for a help group.

The successful candidate will benefit in the form of new knowledge and methods added to his/her toolbox. The project deals with colloidal, cell membranes, and active matter physics, so any candidate profile will find some new knowledge to be gained upon the realisation of the project. We plan to publish the results of the work in high-impact factor journals. The successful candidate will be able to take advantage of all programs in the IPC PAS, including Young Scientists of IPC PAS competition and Mobility of Young Scientists of IPC PAS competition. The Institute provides an opportunity to participate in ERASMUS+ program.

• PhD degree in physics, chemistry, chemical engineering, obtained no earlier than 7 years before the starting year of the employment in the project (this period might be longer due to family reasons (according to NCN rules).
• Good knowledge of statistical physics methods in the condensed (soft) matter physics.
• Analytical and numerical skills and interest: basic level of programming in C or Fortran, Python, Mathematica.

• Extensive (in accordance to research experience) publication list in academic journals and by publishing houses that are reviewed according to international standards.
• Ability to work independently as well as in a group.
• Ability to communicate fluently in English (written and spoken).
• Strong motivation to work and pursue scientific questions, creativity, and analytical thinking.
• Research experience in related fields will be advantageous.

The Recruitment Commission will take into account the following criteria:
• a) competencies of candidates for specific tasks in a research project (max 65 points),
• b) previous scientific achievements of candidates (max 30 points),
• c) awards and distinctions of the candidate resulting from the conducted research (5 points).
The commission evaluates applications on a point scale (max 100 points)
