A mathematical method for irregular hamiltonian systems
Qiuping A. Wang, Wei Li
We present certain mathematical aspects of an information method which was formulated in an attempt to investigate diffusion phenomena. We imagine a regular dynamical hamiltonian s…
Action principle and Jaynes' guess method
Q. A. Wang
A path information is defined in connection with the probability distribution of paths of nonequilibrium hamiltonian systems moving in phase space from an initial cell to different…
Power law distribution of Rényi entropy for equilibrium systems having nonadditive energy
Qiuping A. Wang
Using Rényi entropy, a possible thermostatistics for nonextensive systems is discussed. We show that it is possible to get the -exponential distribution function for nonextensiv…
Pressure effects on the Raman spectrum of
Q. A. Wang, S. Salaun, A. Bulou
The pressure influence on the lattice vibration of has been studied by Raman diffusion up to 17 GPa. Most Raman frequencies increase with increasing pressure. Three singu…
Pressure induced Raman and fluorescence singularities in
Q. A. Wang, A. Bulou, J. Y. Gesland
The pressure effect on the fluoride scheelite laser host is studied at room temperature up to 26 GPa by Raman scattering and up to 40 GPa by fluorescence of doped…
Incomplete information and fractal phase space
Qiuping A. Wang
The incomplete statistics for complex systems is characterized by a so called incompleteness parameter which equals unity when information is completely accessible to our treat…
