Frontiers of Quantum Theory

The Research Group

Nowadays, quantum theory's mathematical formalism is well established and recognised by almost all physicists as a successful model for the calculation of experimental predictions. However, quantum theory and the theory of relativity appear to contradict each other. Moreover, there is no consensus regarding the interpretation of the theory or, consequently, its meaning for our understanding of the world.


The RG Frontiers of Quantum Theory was dedicated to the fringes of quantum theory. In doing so, the limits of its validity were explored in the following contexts:

•    Boundary with classical statistics of open many-body systems, especially quantum decoherence

•    Boundary with the general theory of relativity, especially signatures of quantum noise on large scales

•    Epistemology: How valid are predictions based on a statistical theory? Why is quantum theory a statistical theory?

•    Didactics: Which interpretation of quantum theory is preferred by experts? What knowledge of quantum theory exists among the general public? Do curricula, teacher's workshops, reference works have an acceptable level?


In one of the 2007 issues of the Junge Akademie Magazin (JAM), there was a viewable contribution by the then-spokesperson of the RG on the questions and discussions of the Research Group: Cord Müller, "Der Mond ist doch auch da, wenn niemand nach ihm guckt!", Junge Akademie Magazin Nr. 6, p. 16 f.
