An inverse mass expansion for the mutual information in free scalar QFT at finite temperature
Abstract We study the entanglement entropy and the mutual information in coupled harmonic systems at finite temperature. Interestingly, we find that the mutual information does not vanish at infinite temperature, but it rather reaches a specific finite value, which can be attributed to classical cor...
