Isolated Horizons: the Classical Phase Space
A Hamiltonian framework is introduced to encompass non-rotating (but possibly charged) black holes that are “isolated” near future time-like infinity or for a finite time interval. The underlying space-times need not admit a stationary Killing field even in a neighborhood of the horizon; rather, the physical assumption is that neither matter fields nor gravitational radiation fall across the po...
متن کاملSpace-Times Admitting Isolated Horizons
We characterize a general solution to the vacuum Einstein equations which admits isolated horizons. We show it is a non-linear superposition – in precise sense – of the Schwarzschild metric with a certain free data set propagating tangentially to the horizon. This proves Ashtekar’s conjecture about the structure of spacetime near the isolated horizon. The same superposition method applied to th...
متن کاملStatic Isolated Horizons: SU(2) Invariant Phase Space, Quantization, and Black Hole Entropy
We study the classical field theoretical formulation of static generic isolated horizons in a manifestly SU(2) invariant formulation. We show that the usual classical description requires revision in the non-static case due to the breaking of diffeomorphism invariance at the horizon leading to the non-conservation of the usual pre-symplectic structure. We argue how this difficulty could be avoi...
متن کاملHorizons inside classical lumps.
We investigate the possibility of having horizons inside various classical field configurations. Using the implicit function theorem, we show that models satisfying a certain set of criteria allow for (at least) small horizons within extended matter fields. Gauge and global monopoles and Skyrmions satisfy these criteria. Q-balls and Boson stars are examples which do not and can be shown not to ...
متن کاملQuantum–Mechanical Dualities from Classical Phase Space
The geometry of the classical phase space C of a finite number of degrees of freedom determines the possible duality symmetries of the corresponding quantum mechanics. Under duality we understand the relativity of the notion of a quantum with respect to an observer on C. We illustrate this property explicitly in the case when classical phase space is complex n–dimensional projective space CPn. ...
