Gravitational backreaction
WebSep 8, 2024 · Second, we compute the gravitational backreaction of the quantum fields in the Misner-AdS 3 spacetime, and show that the null chronology horizon turns into a strong, spacelike curvature singularity. This is one of the few controlled, explicit examples where we can see quantum effects change a Cauchy horizon into a spacelike singularity.

General relativity predicts its own demise at singularities but also appears to conveniently shield itself from the catastrophic consequences of such singularities, making them safe. For instance, if strong cosmic censorship were ultimately satisfied, spacetime singularities, although present, would not pose any practical …
WebApr 15, 2024 · This mixing is strongest when the orbital frequency Ω (t), which slowly increases due to gravitational-wave emission, matches the energy gap between the coupled states. During these resonant transitions, the change in the state of the cloud produces a backreaction on the binary’s orbital dynamics.

In this case, the energy scale of the dual field theory is defined as µ = eA(¯y)/R. Now, we discuss the connection between the bulk field and a deformation operator of the dual field theory. burton snowboard company sweatshirt 2010When a particle is considered to have no mass or to have an infinitesimal charge, this can be described as saying that we deal with a probe and that back-reaction is neglected. However, a real object also carries (in general) a mass and a charge itself. These properties imply that the model of the original … See more In theoretical physics, back-reaction (or backreaction) is often necessary to calculate the self-consistent behaviour of a particle or an object in an external field.
