We calculate logarithmic corrections to the Bekenstein-Hawking entropy for three-dimensional AdS black holes and topological de Sitter (TdS) spaces including the Schwarzschild-de Sitter (SdS) solution due to thermal fluctuations. It is found that there is no distinction between the event horizon of AdS black holes and the cosmological horizon of SdS and TdS spaces. We obtain the same correction...
A lot of studies in the information systems, advertising, and marketing literature have shown that for the past two decades online banner ad click-through rate is decreasing steadily (Idemudia et al. 2007). To address this issue, we develop the Visual Perception Model (VP) for Online Target marketing and then conducted an experiment by manipulating the independent variables (i.e. perceived secu...
Commercials (ads) identification and measure their statistics from a video stream is an essential requirement. The duration of a commercial and the timing on which the commercial runs on TV cost differently to the ads owner. Automatic systems that measure these statistics will facilitate the ad owner. This research presents a system that segment semantic videos and identify commercials automati...
We study the wave equation for a massive scalar field in three-dimensional AdS (anti de Sitter) and dS (de Sitter) spaces to find what is the difference and similarity between two spaces. Here the AdS space is provided by the BTZ black hole with J = 0. To investigate its event (cosmological) horizons, we compute the absorption cross section, quasinormal modes, and study the AdS(dS)/CFT correspo...
We investigate the nonlinear realization of partially broken N=2 global supersymmetry in the D = 2 and 3 anti de-Sitter (AdS) space. We particularly study Nambu-Goldstone degrees of freedom for the N=2 AdS supersymmetry partially broken down to N=1 AdS supersymmetry, where we observe a NG fermion of the broken supersymmetry and a NG boson of the internal symmetry which form a NG multiplet. Base...
Two-mode quantized electromagnetic fields can be entangled and admit a large number of coherent states. In this paper, we consider a two-mode system that consists of a two-level atom interacting with a two-mode quantized electromagnetic field, which is initially prepared in an entangled two-mode coherent state, via a nondegenerate two-photon process in a lossless cavity. We study the quantum fl...
[email protected] The Development of ADS Virtual Accelerator Based on XAL Wang Peng-Fei (王鹏飞) Cao Jian-She (曹建社) Ye Qiang (叶强) 1 Institute of High Energy Physics, Chinese Academy of Sciences, Beijing 100049, China 2 University of Chinese Academy of Sciences, Beijing 100049, China Abstract XAL [1-3] is a high level accelerator application framework originally developed by the Spallation Neutron ...
We analytically calculate the quasi-normal modes of various perturbations of spacelike stretched and null warped AdS 3 black holes. From AdS/CFT correspondence, these quasi-normal modes are expected to appear as the poles in momentum space of retarded Green functions of dual operators in CFT at finite temperature. We find that this is indeed the case, after taking into account of the subtle ide...
The two-point Green function of a local operator in CFT corresponding to a massive symmetric tensor field on the AdS background is computed in the framework of the AdS/CFT correspondence. The obtained two-point function is shown to coincide with the two-point function of the graviton in the limit when the AdS mass vanishes.
After an introduction to jet phenomenology and tests of AdS/CFT at LHC we derive the heavy quark drag of a string dangling in a shock metric of AdS space, thus generalizing the AdS/CFT drag calculations in strongly coupled thermal media to momentum loss in both hot and cold nuclear matter.
