A major goal of modern physics is to understand and test the regime where quantum mechanics and general relativity both play a role. I will discuss why looking at composite particles subject to relativistic effects opens new avenues for conceptual insights into the interface between quantum theory and gravity, for new experiments, and will likely be crucial for next-generation high-precision...
In this talk, I will briefly introduce methods to characterize the irreversibility of time-continuous and weak quantum measurements from a thermodynamic viewpoint. By defining a statistical arrow of time for individual realizations of the measurement process, I will show that measurements are absolutely irreversible, similar to the free expansion of a single gas particle in a box. I will...
The quantisation of gravity is widely believed to result in gravitons -- particles of discrete energy that form gravitational waves. But their detection has so far been considered impossible. Here we show that signatures of single gravitons can be observed in laboratory experiments. We show that stimulated and spontaneous single-graviton processes can become relevant for massive quantum...
After more than a 100 yrs of General Relativity, we still argue how we should quantize gravity across all possible energy scales. In this talk, I will highlight some of the unexpected features of gravitational phenomena that might be responsible for the hardness of such a task. In particular, I will argue that quantum field theory might not be the correct framework to embed a non-perturbative...
