THE LOW-FREQUENCY ELECTRIC FIELDS INDUCED IN A SPHERICAL CELL INCLUDING ITS NUCLEUS
LOW-FREQUENCY ELECTRIC FIELDS INDUCED SPHERICAL CELL NUCLEUS
2015/10/16
After a review of work leading to the determination of the electric field induced in the human body when exposed to the electromagnetic field near an extremely-low-frequency high-voltage transmission ...
K-L->pi(0)gamma e(+)e(-) and its relation to CP and chiral tests
Decay in Kuala Lumpur non radiation chiral perturbation theory the quantitative easing policy
2014/12/22
The decay KL→π0γe+e- occurs at a higher rate than the nonradiative process KL→π0e+e-, and hence can be a background to CP violation studies using the latter reaction. It also has interest in its own r...
Scanning Superfluid-Turbulence Cascade by its Low-Temperature Cutoff
Kolmogorov low temperature quantization the vortex line density coefficient of friction
2014/12/19
On the basis of a recently proposed scenario of the transformation of the Kolmogorov cascade into the Kelvin-wave cascade, we develop a theory of low-temperature cutoff. The theory predicts a specific...
N-enlarged Galilei Hopf algebra and its twist deformations
N-enlarged Galilei Hopf algebra Mathematical Physics
2012/5/24
The N-enlarged Galilei Hopf algebra is constructed. Its twist deformations are considered and the corresponding twisted space-times are derived.

Generation of continuous-variable quadripartite square cluster state and its entanglement improvement via quantum feedback
quantum optics continuous variable cluster state feedback
2011/12/15
In this paper, we investigate the generation of continuous-variable quadripartite square cluster state of optical fields and discuss the enhancement of the multipartite entanglement of the cluster sta...
Buckled nano rod - a two state system: quantum effects on its dynamics
Buckled nano rod two state system quantum effects dynamics
2011/8/4
Abstract: We consider a suspended elastic rod under longitudinal compression. The compression can be used to adjust potential energy for transverse displacements from harmonic to double well regime. T...
All metrics have curvature tensors characterised by its invariants as a limit: the ε-property
curvature tensors ε-property General Relativity and Quantum Cosmology
2011/10/8
Abstract: We prove a generalisation of the $\epsilon$-property, namely that for any dimension and signature, a metric which is not characterised by its polynomial scalar curvature invariants, there is...
Semidirect Product of Groupoids, Its Representations and Random Operators
Semidirect Product of Groupoids Representations Random Operators
2011/8/31
Abstract: One of pressing problems in mathematical physics is to find a generalized Poincar\'e symmetry that could be applied to nonflat space-times. As a step in this direction we define the semidire...
Stochastic treatment of finite-N effects in mean-field systems and its application to the lifetimes of coherent structures
Stochastic treatment finite-N effects mean-field systems lifetimes of coherent structures
2011/8/29
Abstract: A stochastic treatment yielding to the derivation of a general Fokker-Planck equation is presented to model the slow convergence towards equilibrium of mean-field systems due to finite-N eff...

2011/7/27
Abstract: We present here a relation of different types of Friedrichs models and their use in the description and comprehension of resonance phenomena. We first discuss the basic Friedrichs model and ...

Transition Probability Its Relatives Quantum Physics
2011/7/27
Abstract: Transition Probability (fidelity) for pairs of density operators can be defined as "functor" in the hierarchy of "all" quantum systems and also within any quantum system. The introduction of...
