Cosmological Constant and Axions in String Theory
String theory axions appear to be promising candidates for explaining cosmological constant via quintessence. In this paper, we study conditions on the string compactifications under which axion quintessence can happen. For sufficiently large number of axions, cosmological constant can be accounted for as the potential energy of axions that have not yet relaxed to their minima. In compactificat...
متن کاملVanishing Cosmological Constant via Gravitational S-Duality
We study S-duality transformations that mix the graviton with various forms of matter. In the case of matter in the form of a 3-form field, the dual of an (A)dS space time – with arbitrary curvature – is seen to be flat Minkowski space time, if the 3-form field has vanishing field strength before the duality transformation. Then we show that the Schwarzschild metric can be obtained as a suitabl...
متن کاملCosmological Constant Seesaw in String/M-Theory
In this paper we extend the Cosmological Constant Seesaw treatment of hepth/0602112 to String/M-Theory where the cosmological constant is finite. We discuss how transitions between different λ, one of Planckian vacuum energy, can give rise to a large M Pl denominator in the Cosmological Constant Seesaw relation discussed by Banks, Motl and Carroll. We apply these ideas to 2d/3d String/M-Theory ...
متن کاملGeneralized Gravitational S-Duality and the Cosmological Constant Problem
We study S-duality transformations that mix the Riemann tensor with the field strength of a 3-form field. The dual of an (A)dS space time – with arbitrary curvature – is seen to be flat Minkowski space time, if the 3-form field has vanishing field strength before the duality transformation. It is discussed whether matter could couple to the dual metric, related to the Riemann tensor after a dua...
متن کاملDuality and the cosmological constant
A dynamical theory is studied in which a scalar field φ in Einstein-Minkowski space is coupled to the four-velocity Nμ of a preferred inertial observer in that space. As a consistent requirement on this coupling we study a principle of duality invariance of the dynamical mass-term of φ at some universal length in the smalldistance regime. In the large-distance regime duality breaking can be int...
