Composite quantum systems under time dilation

Thursday February 8, 2018
3:30 pm

 Presenter:  Magdalena Zych, University of Queensland
 Series:  CQuIC Seminars
 Abstract:  A major goal of modern physics is to understand and test the regime where quantum mechanics and general relativity both play a role. Its new effects are thought to be relevant only at high energies or in strong gravitational fields, beyond the reach of present-day experiments. Here I discuss a novel approach, focused on low-energy but composite quantum systems. Quantum coherence of composite particles can be measurably affected by general relativity even at low-energies and in weak gravitational fields due to time dilation. I will explain the resulting new effects and how they can be tested. I will examine the relevance of the framework of composite quantum systems in curved spacetime for the research in joint foundations of quantum mechanics and general relativity, and for the ongoing efforts to harness quantum phenomena for sensing, communication and information processing.
