Abstract
We study entanglement between two modes of a free bosonic and fermionic field as seen by two accelerating observers at the soft-hair horizon of a four-dimensional supertranslated Schwarzschild black hole. We compute mutual information and entanglement negativity as a measure of entanglement between these two observers and show that their angular dependence at the soft-hair horizon. We also show that for vanishing soft hair function our results are equal to that of an ordinary Schwarzschild black hole case.
