The quantum horizon of the Garfinkle-Horowitz-Strominger dilatonic blackhole

摘要

Treating macro-black hole as quantum states, and using Brown-York's quasi-local gravitational energy definition and Heisenberg uncertainty principle, the GHS black hole's quantum horizon is constructed. The Hawking temperature is computed naturally, and the entropy can also be figured out without introducing the cutoff factor h. The Phi-field mode number is predicted too. The result is consistent with that of the Schwarzschild and R-N black hole.
