Black hole as an Information Eraser
نویسندگان
چکیده
We discuss some puzzles on the identity of black hole entropy by using the Landauer’s principle of information erasure. Especially, we discuss the information freezing on the black hole horizon in terms of information erasing process. We also calculate the quantized black hole mass spectra and entropy assuming that the black hole processes information in unit of bit. The black hole entropy gains a sub-leading contribution proportional to the logarithm of area in addition to the usual areal term without an artificial cutoff. We also argue that the minimum of a black hole mass is √

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 کاملComparison of the Accuracy of Black Hole Algorithms and Gravitational Research and the Hybrid Method in Portfolio Optimization
The main purpose of this research is portfolio optimization in Tehran securities exchange using the black hole algorithm and the Gravitational Research algorithm. We also propose an algorithm named Hybrid Algorithm which combines the two algorithms above to cover the weaknesses of these two algorithms. Finally we compare the results with the Markowitz model and choose the optimal algorithm.<br ...
متن کاملA New Intrusion Detection System to deal with Black Hole Attacks in Mobile Ad Hoc Networks
By extending wireless networks and because of their different nature, some attacks appear in these networks which did not exist in wired networks. Security is a serious challenge for actual implementation in wireless networks. Due to lack of the fixed infrastructure and also because of security holes in routing protocols in mobile ad hoc networks, these networks are not protected against attack...
متن کاملOrganizational Black Hole Theory
There are issues in organizations that require new theoretical formulation. Hence, metaphorical theorizing is used in the study of organizations to interpret them and understand their complexities. In this method, the organization is likened to an entity and one of the key features of that entity is generalized to the organization. It should be borne in mind that most organizational theories ar...
متن کاملTuning of fuzzy logic controller using an improved black hole algorithm for maximizing power capture of ocean wave energy converters
Seas and oceans are the most important sources of renewable energy in the world. The main purpose of this paper is to use an appropriate control strategy to improve the performance of point absorbers. In this scheme, considering the high uncertainty in the parameters of the power take-off system in different atmospheric conditions, a new improved black hole algorithm is introduced to tune fuzzy...
