Spacetime Energy Decreases under World-sheet RG Flow
We study renormalization group flows in unitary two dimensional sigma models with asymptotically flat target spaces. Applying an infrared cutoff to the target space, we use the Zamolodchikov c-theorem to demonstrate that the target space ADM energy of the UV fixed point is greater than that of the IR fixed point: spacetime energy decreases under world-sheet RG flow. This result mirrors the well...
متن کاملTwisted World-Sheet Gravities
This is the first in a series of papers in which I investigate the orbifolds of permutation-type as candidates for new physical string systems at multiples of critical closed-string central charges. Examples include the bosonic orientation orbifolds, the bosonic permutation orbifolds and others, as well as superstring extensions. In this paper I use the extended (twisted) Virasoro algebras of t...
متن کاملScalar fields , bent branes , and RG flow
This work deals with braneworld scenarios driven by real scalar fields with standard dynamics. We show how the first-order formalism which exists in the case of four dimensional Minkowski space-time can be extended to de Sitter or anti-de Sitter geometry in the presence of several real scalar fields. We illustrate the results with some examples, and we take advantage of our findings to investig...
متن کاملRG-Flow, Gravity, and the Cosmological Constant
We study the low energy effective action S of gravity, induced by integrating out gauge and matter fields, in a general class of RS-type string compactification scenarios with exponential warp factors. Our method combines dimensional reduction with the holographic map between between 5-d supergravity and 4-d large N field theory. Using the classical supergravity approximation, we derive a flow ...
متن کاملHow to go with an RG Flow
We apply the formalism of holographic renormalization to domain wall solutions of 5-dimensional supergravity which are dual to deformed conformal field theories in 4 dimensions. We carefully compute oneand two-point functions of the energy-momentum tensor and the scalar operator mixing with it in two specific holographic flows, resolving previous difficulties with these correlation functions. A...
