Reservoir-mediated spin entanglement in the mean-force Gibbs state
Analytic expressions for the two-qubit mean-force Gibbs state show that reservoir-mediated entanglement is highest at low temperature, non-monotonic in coupling strength, and can be enhanced by broadening the reservoir spectral density.
