We try to find a possible origin of the holographic principle in the Lorentz-covariant Yang’s quantized space-time algebra
(YSTA). YSTA, which is intrinsically equipped with short- and long-scale parameters, λ and R, gives a finite number of spatial degrees of freedom for any bounded spatial region, providing a basis for divergence-free
quantum field theory. Furthermore, it gives a definite kinematical reduction of spatial degrees of freedom, compared with
the ordinary lattice space. On account of the latter fact, we find a certain kind of kinematical holographic relation in YSTA,
which may be regarded as a primordial form of the holographic principle suggested so far in the framework of the present quantum
theory that appears now in the contraction limit of YSTA, λ→0 and R→∞.

We propose a new method to reveal a direct transformation from solar energy to solar electricity. Instead of using electricity in the process, we use concentrated solar rays with a crucibleless process to upgrade metallurgical silicon into solar-grade silicon feedstock. 相似文献

A high spatial resolution, phase-sensitive Surface Plasmon Resonance(SPR) sensor based on Extraordinary Optical Transmission (EOT) is proposed to monitor the binding of organic and biological molecules to the silver surface. The 2D nanohole-array configuration is well suited ~br dense integration in a sensor chip. The optical geomeWy is collinear, which simplifies the alignment with respect to the traditional Kretschmann arrangement for SPR sensing. Various design parameters of the device have been studied by simulation. The heterodyne technique is used to improve the sensitivity. The optimization results indicate that the sensor has the advantages of achieving high resolution and a wide dynamic range simuhaneously. 相似文献

In recent work we showed that, for a class of conformal field theories (CFT) with Gauss-Bonnet gravity dual, the shear viscosity to entropy density ratio, eta/s, could violate the conjectured Kovtun-Starinets-Son viscosity bound, eta/s > or = 1/4 pi. In this Letter we argue, in the context of the same model, that tuning eta/s below (16/25)(1/4 pi) induces microcausality violation in the CFT, rendering the theory inconsistent. This is a concrete example in which inconsistency of a theory and a lower bound on viscosity are correlated, supporting the idea of a possible universal lower bound on eta/s for all consistent theories. 相似文献

We present a simple and crude model of galaxies consisting of baryons and neutrinos with spherical symmetry. The baryon matter is rotatinq. in the central region of the galaxy as a nucleus. If the rotational curve of the heavy matter is known from the observational data, then the gravitational potential, and therefore the density distribution in this region, can also be obtained. This enables us to estimate the mass and the radius of the neutrino halo. Furthermore, the condition on the interface of the nucleus-halo will set an upper bound on neutrino mass. If the corresponding parameters duoted in Ref.[10] are adopted, then a value of ≤20eV. for the neutrino mass is obtained. By choosing mv=15eV and a parameter in the rotational curve n=4, one can deduce that neutrino halo radius is about four times the heavy matter radius, and the total mass of neutrinos is about 14 times that of baryons. It seems, that these results are not in contradiction with the observations on the missing mass of the galaxies[6]. 相似文献

The quantum theory of the transverse transport of charged particle systems in a strong, uniform magnetic field is reinvestigated in this article. All such previous theories, based on the Kubo formula in the Landau representation, only considered the second-order term of the collisional expansion series. However, if other high-order terms, especially the so-called reducible diagonal parts, are also considered, another second-order contribution is found, which exactly cancels the one derived prebiously. Hence, within the fxamwork of the usual theory, all the transverse transport coefficients would be identically zero. phis consequence is directly related to the local nature of the Landau eigen states.Only because previous calculations were incomplete did they obtain finite results. 相似文献

In this article, it is pointed out that in a strong magnetic field the usual Boltzmann Equation with Lorentz force term is inconsistent with the fundamental requirements of the general theory of non-equilibrium statistical mechanics. Furthermore, if a collision term corresponding to particles in different gyroorbits is used, we find that all the transport coefficients are exactly zero. 相似文献

The possibility that diquark is a stable object in hadrons and there exists a global supersymmetry between quarks and antidiquarks is discussed. Mesons, baryons and baryoniums can be classified unitedly in the adjoint representation of the super-symmetry group. The united mass splitting formula is obtained based on the snpersymmetry and a naive physical mechanism for symmetry breaking. The mass spectra for baryonium ground states are obtained numerically and may be verified experimentally, Some significant characteristics of baryoniums are discussed and can be used as evident indications of the appearance of加ryoniums. 相似文献
