Long-range enhanced mutual information from inflation

چکیده
The quantum origin of cosmological primordial perturbations is a cornerstone framework in the interplay between gravity and physics. In this paper we study mutual information two spatial regions radiation-dominated universe filled by curvature perturbation field squeezed state. We find an enhancement with respect to usual Minkowski vacuum due momentum modes affected particle production during inflation. This result supports our previous claim existence long-range correlations Primordial Black Holes (PBH) at formation radiation era.

Enhanced RFID Mutual Authentication Scheme based on Synchronized Secret Information
Radio Frequency IDentification (RFID) is an automatic identification system, relying on storing and remotely retrieving data about objects we want to manage using devices called “RFID tag”. Even though RFID system is widely useful for industrial and individual applications, RFID tag has a serious privacy problem, i.e., traceability. To protect users from tracing, we propose an RFID mutual authe...
متن کاملEnhanced Multimodality Image Registration Based On Mutual Information
Different modalities can be achieved by the maximization of suitable statistical similarity measures within a given class of geometric transformations . The registration functions are less sensitive to low sampling resolution, do not contain incorrect global maxima which are sometimes found in the mutual information. This paper proposes a novel and straightforward multimodal image registration ...
متن کاملLearning from Examples with Quadratic Mutual Information
This paper discusses a novel algorithm to train nonlinear mappers with information theoretic criteria (entropy or mutual information) directly from a training set. l’he method is based on a Parzen window estimator and uses Renyi’s quadratic definition of entropy and a distance measure based on the Cauchy-Schwartz inequality. We apply the algorithm to the difficult problem of vehicle pose estima...
متن کاملClustering of a Number of Genes Affecting in Milk Production using Information Theory and Mutual Information
Information theory is a branch of mathematics. Information theory is used in genetic and bioinformatics analyses and can be used for many analyses related to the biological structures and sequences. Bio-computational grouping of genes facilitates genetic analysis, sequencing and structural-based analyses. In this study, after retrieving gene and exon DNA sequences affecting milk yield in dairy ...
متن کاملOn Classification of Bivariate Distributions Based on Mutual Information
Among all measures of independence between random variables, mutual information is the only one that is based on information theory. Mutual information takes into account of all kinds of dependencies between variables, i.e., both the linear and non-linear dependencies. In this paper we have classified some well-known bivariate distributions into two classes of distributions based on their mutua...
