Coexisting vacua and effective gravity
Our Universe is perhaps a domain separated by physical phase boundaries from other domain-Universes with different vacuum energy density (cosmological constant) and matter content. The coexistence of different quantum vacua can then be regulated by the exchange of global fermionic charges between the vacua, such as baryonic and leptonic charge, or by fermion zero modes on the phase boundary. An...
متن کاملQuantum Gravity, Flavour Vacua and Supersymmetry
I review a novel and non-perturbative way of breaking Supersymmetry in the flavour sector of electrically neutral particles, as a result of flavour mixing in the presence of stringy quantum gravity space-time foam backgrounds that violate Lorentz and CPT symmetries. In these models, part of the mixing may itself be induced dynamically by the interactions of the flavoured particles with the spac...
متن کاملScalar - tensor gravity in an accelerating universe
We consider scalar-tensor theories of gravity in an accelerating universe. The equations for the background evolution and the perturbations are given in full generality for any parametrization of the Lagrangian, and we stress that apparent singularities are sometimes artifacts of a pathological choice of variables. Adopting a phenomenological viewpoint, i.e., from the observations back to the t...
متن کاملGauge/gravity correspondence in accelerating universe
We discuss time-dependent backgrounds of type IIB supergravity realizing gravitation duals of gauge theories formulated in de Sitter space-time as a tool of embedding de Sitter in a supergravity. We show that only the gravitational duals to non-conformal gauge theories are sensitive to a specific value of a Hubble parameter. We consider two nontrivial solutions of this type: a gravity dual to s...
متن کاملAccelerating Universe in Modified Theories of Gravity
We study cosmologies in modified theories of gravity considering Lagrangian density f(R) which is a polynomial function of scalar curvature (R) in the Einstein-Hilbert action in vacuum. The field equation obtained from the modified action corresponding to a Robertson-Walker metric is highly non-linear and not simple enough to obtain analytic solution. Consequently we adopt a numerical technique...
