It is shown that its singular point represents an attractor for classical solutions and the stationary value of the field may occur distant from the minimum of the potential. In this paper properties of universes with such stationary states are considered. We reveal that such state can be responsible for modern dark energy density.

Charged Perfect Fluid and Scalar Field Coupled to Gravity
Charged perfect fluid with vanishing Lorentz force and massless scalar field is studied in the case of stationary cylindrically symmetric spacetime. The scalar field can depend both on radial and longitudinal coordinates. Solutions are found and classified according to scalar field gradient and magnetic field relationship. Their physical and geometrical properties are examined and discussion of...

We study the entropy of extremal four dimensional black holes and five dimensional black holes and black rings is a unified framework using Sen’s entropy function and dimensional reduction. The five dimensional black holes and black rings we consider project down to either static or stationary black holes in four dimensions. The analysis is done in the context of two derivative gravity coupled ...

Integrable models of 1 + 1 dimensional gravity coupled to scalar and vector fields are briefly reviewed. A new class of integrable models with nonminimal coupling to scalar fields is constructed and discussed.
متن کاملbeta functions of a scalar theory coupled to gravity.
We study a scalar field theory coupled to gravity on a flat background, below Planck’s energy. Einstein’s theory is treated as an effective field theory. Within the context of Wilson’s renormalization group, we compute gravitational corrections to the beta functions and the anomalous dimension of the scalar field, taking into account threshold effects.
متن کاملOn the absence of scalar hair for charged rotating black holes in non-minimally coupled theories S SEN and N BANERJEE
Recently there has been a considerable resurgence in the no scalar hair theorem for black holes. Investigations regarding no hair theorem, however, had started about thirty years ago [1]. Inspired by Israel’s uniqueness theorem for Schwarzschild and Reissner–Nordstrom black holes [2] and Carter [3] and Wald’s [4] uniqueness theorem for Kerr black holes, Wheeler anticipated that gravitational co...
