Connection and Dispersion of ComputationJun 27 2011Aug 09 2011This paper talk about the influence of Connection and Dispersion on Computational Complexity. And talk about the HornCNF's connection and CNF's dispersion, and show the difference between CNFSAT and HornSAT. First, I talk the relation between MUC decision ... More

Shift of Fermi level by substitutional impurity-atom doping in diamond and cubic- and hexagonal-boron nitrides II. Generalized Gradient ApproximationDec 21 2014In succession to the first paper (arXiv 1406.6204v5), the impurity-atom concentrations when the Fermi levels are either at the valence band maximum (VBM) or the conduction band minimum (CBM) were identified for diamond, cubic boron nitride (cBN), and ...

Violation of time symmetryJun 09 2004Nov 28 2008Recently, [{arXiv:0810.3134}] is accepted and published. We would like to study the relation between a local realistic theory and commutativity of observables in a finite-dimensional space. We would like to conjecture that a realistic theory of the Bell ... More

Existence of compatible systems of lisse sheaves on arithmetic schemesSep 19 2015Deligne conjectured that a single l-adic lisse sheaf on a normal variety over a finite field can be embedded into a compatible system of l'-adic lisse sheaves with various l'. Drinfeld used Lafforgue's result as an input and proved this conjecture when ... More

Possibility of ferromagnetic neutron matterDec 22 2014Jan 13 2015We study ferromagnetism at high density of neutrons in the QCD hadron phase, by using the simplest chiral effective model incorporating magnetic fields and the chiral anomaly. Under the assumption of spatial homogeneity, we calculate the energy density ... More

Holographic Nuclei : Supersymmetric ExamplesOct 13 2009Nov 15 2009We provide a dual gravity description of a supersymmetric heavy nucleus, following the idea of our previous paper arXiv:0809.3141. The supersymmetric nucleus consists of a merginal bound state of $A$ baryons distributed over a ball in 3 dimensions. In ... More

The shape of nonabelian D-branesJan 08 2004Jan 29 2004We evaluate bulk distribution of energies, pressures and various D-brane/F-string charges generated by nontrivial matrix configurations in nonabelian D-brane effective field theories, using supergravity source density formulas derived originally in Matrix ...

Born-Infeld Dynamics in Uniform Electric FieldMay 22 1999Jun 09 1999We investigate various properties of classical configurations of the Born-Infeld theory in a uniform electric field. This system is involved with dynamics of (F,Dp) bound states, which are bound states of fundamental strings and Dp-branes. The uniform ... More
