Chinese scientists realize quantum simulation of the Unruh effect

Quantum mechanics and relativity theory are two pillars of modern physics. With their amalgamation, many novel phenomena have been identified. For example, the Unruh effect is one of the most significant outcomes of quantum field theory. This effect serves as an important tool to investigate phenomena such as thermal emission of particles from black holes and cosmological horizons. It has been 40 years since the discovery of the Unruh effect, but this effect is too weak to be observed using curr
