Quantum noise in the collective abstraction reaction A+B2→AB+B

We demonstrate theoretically that the collective abstraction reaction A+B2→AB+B can be realized efficiently with degenerate bosonic or fermionic matter waves. We show that this is dominated by quantum fluctuations, which are critical in triggering its initial stages with the appearance of macroscopic nonclassical correlations of the atomic and molecular fields as a result. This study opens up a promising new regime of quantum-degenerate matter-wave chemistry.
