The Unruh effect is a seminal result which illustrates the relative character of the particle concept in QFT, but its validity for extended systems is debated. Here, the authors show how a uniformly accelerated extended system of two coupled spins will evolve to a Gibbs thermal state at the Unruh temperature.
