Entropy, Vol. 24, Pages 1411: Final-State Condition and Dissipative Quantum Mechanics (Entropy)

Unitarity demands that the black-hole final state (what remains inside the event horizon at complete evaporation) must be unique. Assuming a UV theory with infinitely many fields, we propose that the uniqueness of the final state can be achieved via a mechanism analogous to the quantum-mechanical description of dissipation.
