Fisher's zeros as boundary of RG flows in complex coupling space
boundary RG flows complex coupling space
2010/12/24
We discuss the possibility of extending the RG flows to complex coupling spaces. We argue that the Fisher's zeros are located at the boundary of the complex basin of attraction of IR fixed points. We...

Comparing space+time decompositions the post-Newtonian limit
2010/12/27
We compare the Arnowitt-Deser-Misner (ADM) field decomposition with the Non-Relativistic Gravitational (NRG) fields for the purpose of computing the two-body post-Newtonian (PN) effective action withi...

The determination of the two-body density functional from its one-body density is achieved for Moshinsky's harmonium model, using a phase-space formulation, thereby resolving its phase dilemma. The c...
Forty-five years after the point de d\'epart [1] of density functional theory, its applications in chemistry and the study of electronic structures keep steadily growing. However, the precise form of...
Space-Time Compactification, Non-Singular Black Holes, Wormholes and Braneworlds via Lightlike Branes
Space-Time Compactification Non-Singular Black Holes
2010/12/24
We describe a concise general scheme for constructing solutions of Einstein-Maxwell-Kalb-Ramond gravity-matter system in bulk space-time interacting self-consistently with one or more (widely separate...
Conformal field theories in anti-de Sitter space
Conformal field theories anti-de Sitter space
2010/12/24
In this paper we discuss the dynamics of conformal field theories on anti-de Sitter space, focussing on the special case of the N=4 supersymmetric Yang-Mills theory on AdS_4. We argue that the choice...
On the structure of the S-matrix in general boundary quantum field theory in curved space
the S-matrix quantum field theory
2010/12/23
We use the general boundary formulation (GBF) of quantum field theory to compute the S-matrix for a general interacting scalar field in curved spacetime. This S-matrix is obtained as the asymptotic li...
The Backreaction of Anti-M2 Branes on a Warped Stenzel Space
Anti-M2 Branes Warped Stenzel Space
2010/12/23
We find the superpotential governing the supersymmetric warped M-theory solution with a transverse Stenzel space found by Cvetic, Gibbons, Lu and Pope in hep-th/0012011, and use this superpotential to...
Matrix Model for membrane and dynamics of D-Particles in a curved space-time geometry and presence of form fields
Matrix Model membrane dynamics D-Particles
2010/12/23
We study dynamics of a membrane and its matrix regularisation. We present the matrix regularisation for a membrane propagating in a curved space-time geometry in the presence of an arbitrary 3-form fi...
We apply the nonstandard loop quantum cosmology method to quantize a flat FRW cosmological model with a free scalar field and the cosmological constant $\Lambda>0$. Modification of the Hamiltonian in ...
Lorentz invariance, nonzero minimal uncertainty in position, and inhomogeneity of space at the Planck scale
Lorentz invariance nonzero minimal uncertainty
2010/12/24
The suspicion that the existence of a minimal uncertainty in position measurements violates Lorentz invariance seems unfounded. It is shown that the existence of such a nonzero minimal uncertainty in...
Scalar Field in Non-commutative Curved Space time
Scalar Field Non-commutative Curved Space time
2010/12/24
We will study the theory of scalar field in non-commutative curved space time (NCCST) with a percussionist who has been found by Mebaraki. In this paper, the motion equation of the scalar field will ...
We explore in detail the prospects of obtaining a four-dimensional de Sitter universe in classical supergravity models with warped and time-independent extra dimensions, presenting explicit cosmologic...
