Towards Nonadditive Quantum Information Theory
Sumiyoshi Abe, A. K. Rajagopal
A definition of the nonadditive (nonextensive) conditional entropy indexed by q is presented. Based on the composition law in terms of it, the Shannon-Khinchin axioms are generaliz…
Statistical Mechanical Foundations for Systems with Nonexponential Distributions
A. K. Rajagopal, Sumiyoshi Abe
Traditionally the exponential canonical distributions of Gibbsian statistical mechanics are given theoretical justification in at least four different ways: steepest descent method…
LASCO Measurements of the Energetics of Coronal Mass Ejections
Angelos Vourlidas, Prasad Subramanian, K. P. Dere +1
We examine the energetics of Coronal Mass Ejections (CMEs) with data from the LASCO coronagraphs on SOHO. The LASCO observations provide fairly direct measurements of the mass, vel…
74 MHz-VLA-Observation of Coma Berenices with Subarcminute Resolution -- Observation, Data Reduction, and Preliminary Results
T. A. Ensslin, Kronberg, R. A. Perley +1
We report on an ongoing project to map a 15 degree x 15 degree region in Coma Berenices with the new 74 MHz receiver system of the VLA. The field is centered on the Coma cluster of…
