A particular type of coupling of the dilaton field to the metric is shown to admit a simple geometric interpretation in terms of a volume element density independent from the metric. For dimension n = 4 two families of either magnetically or electrically charged static spherically symmetric solutions to the Maxwell-Einstein-Dilaton field equations are derived. Whereas the metrics of the "magnetic" spacetimes are smooth, geodesically complete and have the topology of a wormhole, the "electric… 
The ultrarelativistic limit of 2D dilaton gravity and its energy–momentum tensor
The ultrarelativistic limit of two-dimensional dilaton gravity is presented and its associated (anti-)self-dual energy–momentum tensor is derived. It is localized on a null line, although the line
Ricci Flow Gravity
A theory of gravitation is proposed, modeled after the notion of a Ricci flow. In addition to the metric an independent volume enters as a fundamental geometric structure. Einstein gravity is
Metric measure space as a framework for gravitation
In this manuscript, we show how conformal invariance can be incorporated in a classical theory of gravitation, in the context of metric measure space. Metric measure space involves a geometrical
Stability of thin-shell wormholes with spherical symmetry
In this article, the stability of a general class of spherically symmetric thin-shell wormholes is studied under perturbations preserving the symmetry. For this purpose, the equation of state at the
A conformally invariant theory of gravitation in metric measure space
In this manuscript, a conformally invariant theory of gravitation in the context of metric measure space is studied. The proposed action is invariant under both diffeomorphism and conformal
Thin-shell wormholes in dilaton gravity
In this work we construct charged thin-shell Lorentzian wormholes in dilaton gravity. The exotic matter required for the construction is localized in the shell and the energy conditions are satisfied
The role of N* resonances in the K+p → K+K+Λ reaction
In this work, we investigate the reaction K+p ? K+K+? for K+ beam momentum from threshold to 8 GeV within an effective Lagrangian approach where the contributions to the amplitudes are taken into

On a class of stable, traversable Lorentzian wormholes in classical general relativity
It is known that Lorentzian wormholes must be threaded by matter that violates the null energy condition. We phenomenologically characterize such exotic matter by a general class of microscopic
Charged black holes in string theory.
TLDR
A family of solutions to low-energy string theory representing static, spherically symmetric charged black holes is described, and the extremal charged "black holes" are found to be geodesically complete spacetimes with no event horizons and no singularities.
Scalar-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

A unified framework for black holes and traversible wormholes is described, where both are locally defined by outer trapping horizons, two-way traversible for wormholes and one-way traversible for
