Internal and External Fluctuation Activated Non-equilibrium Reactive Rate Process
The activated rate process for non-equilibrium open systems is studied taking
into account both internal and external noise fluctuations in a unified way.
The probability of a particle diffusing passing over the saddle point and the
rate constant together with the effective transmission coefficient are
calculated via the method of reactive flux. We find that the complexity of
internal noise is always harmful to the diffusion of particles. However the
external modulation may be beneficial to the rate process.Comment: 10 pages, 1 figure (containing 2 subgraphs). arXiv admin note: text

A Quantum Quasi-Harmonic Nonlinear Oscillator with an Isotonic Term
The properties of a nonlinear oscillator with an additional term ,
characterizing the isotonic oscillator, are studied. The nonlinearity affects
to both the kinetic term and the potential and combines two nonlinearities
associated to two parameters, and , in such a way that for
all the characteristics of of the standard isotonic system are
recovered. The first part is devoted to the classical system and the second
part to the quantum system. This is a problem of quantization of a system with
position-dependent mass of the form , with a
-dependent non-polynomial rational potential and with an additional
isotonic term. The Schr\"odinger equation is exactly solved and the
-dependent wave functions and bound state energies are explicitly
obtained for both .Comment: two figure
Muon Anomalous Magnetic Moment and Lepton Flavor Violating Tau Decay in Unparticle Physics
We study effects of unparticle physics on muon g-2 and LFV tau decay
processes. LFV interactions between the Standard Model sector and unparticles
can explain the difference of experimental value of muon g-2 from the Standard
Model prediction. While the same couplings generate LFV tau decay, we found
that LFV coupling can be of O(0.1 ... 1) without conflict with experimental
bounds of LFV tau decay if the scaling dimension of unparticle operator d_{U} >
