Field sources for Simpson-Visser spacetimes

چکیده
Simpson-Visser (SV) space-times are the simplest globally regular modifications of Schwarzschild, Reissner-Nordstrom and other blak-hole solutions general relativity. They smoothly interpolate between these black holes traversable wormholes. After a brief presentation Schwarzschild-like Reissner-Nordstrom-like SV geometries, including their Carter-Penrose diagrams, we show that any static, spherically symmetric metric can be obtained as an exact solution to Einstein field equations sourced by combination minimally coupled phantom scalar with nonzero potential $V(\phi)$ magnetic in framework nonlinear electrodynamics Lagrangian $\mathcal {L(F)}$, $\mathcal{F} = F_{\mu\nu} F^{\mu\nu}$ (in standard notations). Explicit forms {L(F)}$ presented for cases metrics.

Construction of Sources for Majumdar-Papapetrou Spacetimes
We study Majumdar-Papapetrou solutions for the 3+1 Einstein-Maxwell equations, with charged dust acting as the external source for the fields. The spherically symmetric solution of Gürses is considered in detail. We introduce new parameters that simplify the construction of class C1, singularity-free geometries. The arising sources are bounded or unbounded, and the redshift of light signals all...
متن کاملScalar Field Quantum Inequalities in Static Spacetimes
We discuss quantum inequalities for minimally coupled scalar fields in static spacetimes. These are inequalities which place limits on the magnitude and duration of negative energy densities. We derive a general expression for the quantum inequality for a static observer in terms of a Euclidean two-point function. In a short sampling time limit, the quantum inequality can be written as the flat...
متن کاملSolving quantum field theories via curved spacetimes
© 2009 American Institute of Physics, S-0031-9228-0901-010-2 Eleven years ago several theorists proposed a remarkable correspondence between two seemingly different kinds of theories.1 It is often called a duality because it is an equivalence between two different, “dual” descriptions of the same physics. On one side of the duality are certain quantum field theories (QFTs)—for example, Yang–Mil...
متن کاملEffective quantum field theories in general spacetimes
We introduce regular charts as physical reference frames in spacetime, and we show that general spacetimes can always be fully captured by regular charts. Effective quantum field theories (QFTs) can be conveniently defined in regular reference frames, and the definition is independent of specific background metric and independent of specific regular reference frame. As a consequence, coupling t...
متن کاملObservables for spacetimes with two Killing field symmetries.
The Einstein equations for spacetimes with two commuting spacelike Killing field symmetries are studied from a Hamiltonian point of view. The complexified Ashtekar canonical variables are used, and the symmetry reduction is performed directly in the Hamiltonian theory. The reduced system corresponds to the field equations of the SL(2,R) chiral model with additional constraints. On the classical...
