英文摘要: Abstract(#br)The exploration of quantum phenomena in a curved spacetime is an emerging interdisciplinary area at the interface between general relativity 1 – 4 , thermodynamics 4 – 6 and quantum information 7 , 8 . One famous prediction in this field is Unruh thermal radiation 3 —the manifestation of thermal radiation from a Minkowski vacuum when viewed in an accelerating reference frame. Here, we report the experimental observation of a matter field with thermal fluctuations that agree with Unruh’s predictions. The matter field is generated within a framework for the simulation of quantum physics in a non-inertial frame, based on Bose–Einstein condensates that are parametrically modulated 9 to make their evolution replicate the...
