Description

Backaction plays a fundamental role in measurements made on quantum systems. In this talk I will discuss the role of backaction in quantum simulators on analogue spacetime, presenting both a non-perturbative treatment of backaction for an analogue realization of the circular Unruh effect and a general analogy incorporating perturbative backaction for Unruh-deWitt detectors in (2+1) dimensions. I will compare the two treatments, and then comment on the role of backaction for extracting a signature of the Unruh effect beyond the standard quantum limit.
