Wormholes and Global Symmetries*
نویسنده
چکیده
We examine the effects that topological fluctuations in the structure of space-time have on the global U(1) symmetry of a scalar field theory. When the symmetry is not spontaneously broken we find wormhole solutions which break the U(1) symmetry despite the fact that they have infinite euclidean action. In the case where the symmetry is spontaneously broken we find wormhole solutions of finite action.

Can Gravitational Instantons Really Constrain Axion Inflation?
Axions play a central role in inflationary model building and other cosmological applications. This is mainly due to their flat potential, which is protected by a global shift symmetry. However, quantum gravity is known to break global symmetries, the crucial effect in the present context being gravitational instantons or Giddings-Strominger wormholes. We attempt to quantify, as model-independe...
متن کاملGravity and global symmetries.
There exists a widely spread notion that gravitational effects can strongly violate global symmetries. If this is correct, it may lead to many important consequences. We will argue, in particular, that nonperturbative gravitational effects in the axion theory lead to a strong violation of CP invariance unless they are suppressed by an extremely small factor g <∼ 10−82. One could hope that this ...
متن کاملGeneral Dynamic Wormholes and Violation of the Null Energy Condition
Although wormholes can be treated as topological objects in spacetime and from a global point-of-view, a precise definition of what a wormhole throat is and where it is located can be developed and treated entirely in terms of local geometry. This has the advantage of being free from unnecesary technical assumptions about asymptotic flatness, and other global properties of the spacetime contain...
متن کاملWormholes and Cosmic Strings
A gravitational scenario is proposed where the euclidean action is invariant under the isotropic and homogeneous version of the euclidean U(1) group of local transformations of the scale factor and scalar matter field, interpreting the trace of the second fundamental form as the gauge field. The model allows spontaneous breakdown of some involved symmetries, including possibly diffeomorphism in...
متن کاملThe Symmetries of Equivalent Lagrangian Systems and Constants of Motion
In this paper Mathematical structure of time-dependent Lagrangian systems and their symmetries are extended and the explicit relation between constants of motion and infinitesimal symmetries of time-dependent Lagrangian systems are considered. Starting point is time-independent Lagrangian systems ,then we extend mathematical concepts of these systems such as equivalent lagrangian systems to th...
