Black Holes and Quantum Mechanics
The motion of a particle near the RN black hole horizon is described by conformal mechanics. Models of this type have no ground state with vanishing energy. This problem was resolved in past by a redefinition of the Hamiltonian which breaks translational time invariance but gives a normalizable ground state. We show that this change of the Hamiltonian is a quantum mechanical equivalent of the c...

متن کاملQuantum anomaly in molecular physics.
The interaction of an electron with a polar molecule is shown to be the simplest realization of a quantum anomaly in a physical system. The existence of a critical dipole moment for electron capture and formation of anions, which has been confirmed experimentally and numerically, is derived. This phenomenon is a manifestation of the anomaly associated with quantum symmetry breaking of the class...
متن کاملThe Quantum Mechanics of Black Holes
T he first 30 years Of this century saw the emergence of three theo ries that radically altered man's view of physics and of reality itself. Physicists are still trying to explore their implications and to fit them together. The three theories were the special theo ry of relativity (1905), the general the ory of relativity (1915) and the theory of quantum mechanics (c. 1926). Albert Einstein...
متن کاملTHE QUANTUM PHYSICS OF BLACK HOLES: Results from String Theory
We review recent progress in our understanding of the physics of black holes. In particular, we discuss the ideas from string theory that explain the entropy of black holes from a counting of microstates of the hole, and the related derivation of unitary Hawking radiation from such holes.
