Reversing the direction of heat flow using quantum correlations

Reversing the direction of heat flow using quantum correlations

The presence of correlations can strongly affect the evolution of a quantum system. Here, the authors directly observe differences in the dynamics of two spins-1/2 systems in an NMR setup depending on the correlations of the initial state, including differences in energy flow and mutual information.
