Generalized McVittie geometry in Horndeski gravity with matter
نویسندگان
چکیده
We investigate McVittie and generalized solutions for Horndeski gravity with a spatially homogeneous gravitational scalar field, which is stealth at small scales near the central object but, large scales, sources FLRW universe in inhomogeneity embedded. Unlike previous studies, we include matter obtain extended cuscuton model. The possible configurations are classified according to time-dependence of coupling, radial energy flow, accretion rate onto object, Hubble rate.

Generalized 2d dilaton gravity with matter fields
We extend the classical integrability of the CGHS model of 2d gravity [1] to a larger class of models, allowing the gravitational part of the action to depend more generally on the dilaton field and, simultaneously, adding fermion– and U(1)–gauge–fields to the scalar matter. On the other hand we provide the complete solution of the most general dilaton–dependent 2d gravity action coupled to chi...
متن کاملIntegrating Geometry in General 2D Dilaton Gravity with Matter
General 2d dilaton theories, containing spherically symmetric gravity and hence the Schwarzschild black hole as a special case, are quantized by an exact path integral of their geometric (Cartan-) variables. Matter, represented by minimally coupled massless scalar fields is treated in terms of a systematic perturbation theory. The crucial prerequisite for our approach is the use of a temporal g...
متن کاملGeneralized Curvature-Matter Couplings in Modified Gravity
In this work, we review a plethora of modified theories of gravity with generalized curvature-matter couplings. The explicit nonminimal couplings, for instance, between an arbitrary function of the scalar curvature R and the Lagrangian density of matter, induces a non-vanishing covariant derivative of the energy-momentum tensor, implying non-geodesic motion and, consequently, leads to the appea...
متن کاملQuantum geometry of 2 d gravity coupled to unitary matter
We show that there exists a divergent correlation length in 2d quantum gravity for the matter fields close to the critical point provided one uses the invariant geodesic distance as the measure of distance. The corresponding reparameterization invariant two-point functions satisfy all scaling relations known from the ordinary theory of critical phenomena and the KPZ exponents are determined by ...
متن کاملGravity duals to deformed SYM theories and Generalized Complex Geometry
We analyze the supersymmetry conditions for a class of SU(2) structure backgrounds of Type IIB supergravity, corresponding to a specific ansatz for the supersymmetry parameters. These backgrounds are relevant for the AdS/CFT correspondence since they are suitable to describe mass deformations or beta-deformations of four-dimensional superconformal gauge theories. Using Generalized Complex Geome...
