Mapping theorem and Green functions in Yang-Mills theory
Mapping theorem Green functions Yang-Mills theory
2010/12/23
It is shown how, starting from a mapping theorem recently proved between massless quartic scalar field theory and Yang-Mills theory, both two-point functions and spectrum of the Yang-Mills theory can ...
Cosmic acceleration and the challenge of modifying gravity
Cosmic acceleration modifying gravity
2010/12/24
briefly discuss the challenges presented by attempting to modify general relativity to obtain an explanation for the observed accelerated expansion of the universe. Foremost among these are the quest...
On the Efetov-Wegner terms by diagonalizing a Hermitian supermatrix
Efetov-Wegner terms diagonalizing Hermitian supermatrix
2010/12/24
The diagonalization of Hermitian supermatrices is studied. Such a change of coordinates is inevitable to find certain structures in random matrix theory. However it still poses serious problems since ...
Haag's theorem states that if a quantum field theory is Lorentz invariant and irreducible, there is no interaction picture. But if we construct quantum field theory on a discrete lattice spacetime, it...

We present an update of an on-going project to determine the disconnected contributions to hadronic structure, specifically, the scalar matrix element and the quark contribution to the spin of the nuc...

We obtain a family of supersymmetric solutions of type IIB supergravity with dynamic SU(2) structure, which describe the local geometry near a stack of four D7-branes and one O7-plane wrapping a rigi...
Hawking Radiation and Entropy from Horizon Degrees of Freedom
Hawking Radiation Entropy Horizon Degrees
2010/12/24
We study the thermodynamic properties of horizons using the dynamical description of the gravitational degrees of freedom at a horizon derived in an earlier work. We use the action of the horizon degr...
Proof of universality of electrical conductivity at finite chemical potential
electrical conductivity finite chemical potential
2010/12/23
It was proposed in arXiv:1008.2944 that, for certain gauge theories with gravity duals, electrical conductivity at finite chemical potential is universal. Here we provide a general proof that, when m...
Minimal conditions for the existence of a Hawking-like flux
the existence Hawking-like flux
2010/12/27
We investigate the minimal conditions that an asymptotically flat general relativistic spacetime must satisfy in order for a Hawking-like Planckian flux of particles to arrive at future null infinity...
We study moduli space stabilization of a class of BPS configurations from the perspective of the real intrinsic Riemannian geometry. Our analysis exhibits a set of implications towards the stability ...
An application of the variational analysis to calculate the meson spectral functions
the variational analysis the meson spectral functions
2011/1/6
We present a new method to calculate meson spectral functions (SPFs) on the lattice based on a variational method. Because, on a finite volume lattice, the meson SPFs have discrete spectra only, a sui...

Hierarchies of Susy Splittings and Invisible Photinos as Dark Matter
Susy Splittings Invisible Photinos Dark Matter
2010/12/24
We explore how to generate hierarchies in the splittings between superpartners. Some of the consequences are the existence of invisible components of dark matter, new inflaton candidates, invisible mo...
