A major goal of modern physics is to understand and test the regime where quantum mechanics and general relativity both play a role. However, its distinctive effects are typically relevant at high energies or strong gravitational fields, beyond the reach of present-day experiments. In this seminar I will discuss a different approach, focused on low-energy but composite quantum systems. Internal dynamics of composite systems can act as a sensitive probe of relativistic effects even at low-energies and in weak gravitational fields -- I will explain what quantum and general relativistic effects can arise for such systems and how they can be tested. I will outline the broader relevance of this approach for the research on joint foundations of quantum mechanics and general relativity, and for the future quantum-enhanced technologies such as metrology and sensing, or information processing.
