科隆大学招收物理学博士
Granular Matter Group, Institute for Theoretical Physics
The University of Cologne is one of the largest and most research-intensive universities in Germany, offering a wide range of subjects. With its six faculties and its interfaculty centres, it offers a broad spectrum of scientific disciplines and internationally outstanding profile areas, supported by the administration with its services.
The Granular Matter Group investigates the microscopic mechanisms that determine the collective mechanical properties of large particulate systems. We study transitions between granular solid-/fluid-/gas-like states. In a current experiment on the International Space Station (ISS), sound waves are used to probe the continuum limit of bead packing ensembles under fluctuating contact-forces and topologies.
Your Tasks
Data analysis of an ongoing ISS experiment
Ground reference measurements and refinement of parameters for new runs of the ISS experiment
Laboratory experiments in cooperation with DLR Cologne
Combining results of ISS and ground data with externally provided material calibration data to obtain empirical laws
Theoretical analysis based on Effective Medium Theory
Identifying and testing relevant mechanisms on different length scales: nonlinear force-laws, force-chain topology, distribution of force fluctuations, crystalline domains
Exploring extensions of current theories for disordered granular matter
Your Profile
Physics Master or equivalent
Previous experience of working in physics labs with electronic equipment (microcontrollers, oscilloscopes, etc)
Programming languages: C, C++, git
Experience with Linux is beneficial
Fluent in English, possibly German
Capable of working in international, multidisciplinary teams
Resilient and adaptive to high levels of stress and workloads
