Black holes as mirrors: quantum information in random subsystems
We study information retrieval from evaporating black holes, assuming that the internal dynamics of a black hole is unitary and rapidly mixing, and assuming that the retriever has unlimited control over the emitted Hawking radiation. If the evaporation of the black hole has already proceeded past the “half-way” point, where half of the initial entropy has been radiated away, then additional qua...
متن کاملHighly absorbing black Mg and rare-earth-Mg switchable mirrors
Apart from a reflecting and a transparent state, rare-earth-Mg alloys ~RE-Mg! exhibit also a highly absorbing, black state during loading with hydrogen. The occurrence of such a black state is due to the disproportionation into subwavelength size REH21e and Mg grains during the first hydrogen loading. While the optical properties of REHx change continuously with a further increase in hydrogen c...
متن کاملRicardo Baeza - Yates Julien
Time is an important dimension of any information space. It can be very useful for a wide range of information retrieval tasks such as document exploration, similarity search, summarization, and clustering. Traditionally, information retrieval applications do not take full advantage of all the temporal information embedded in documents to provide alternative search features and user experience....
متن کاملMoving Mirrors , Black Holes , Hawking Radiation and All
In this talk I show how to canonically quantize a massless scalar field in the background of a Schwarzschild black hole in Lemâitre coordinates and then present a simplified derivation of Hawking radiation based upon this procedure. The key result of quantization procedure is that the Hamiltonian of the system is explicitly time dependent and so problem is intrinsically non-static. From this it...

Coronary heart disease is the leading cause of death in the United States. An alternate therapy is needed to treat the 180,000 people each year who require coronary artery bypass surgery. Several different strategies have been explored to develop vascular graft substitutes, but so far all have proven unsatisfactory. Current engineered vessels lack sufficient strength or require many weeks to be...
