Genuine tripartite entanglement of W state subject to Hawking effect of a Schwarzschild black hole
نویسندگان
چکیده
Abstract We study the genuine tripartite entanglement (GTE), one-tangle and two-tangle of W state fermionic fields in background a Schwarzschild black hole. find that, with increase Hawking temperature, GTE first decreases then tends to zero, while GHZ freezes. also that effect can completely destroy state, freezing phenomenon appears growth temperature. These results are helpful guide us select appropriate quantum states resources deal relativistic information tasks.

Interaction of Hawking radiation with static sources outside a Schwarzschild black hole
We show that the response rate of ~i! a static source interacting with Hawking radiation of a massless scalar field in Schwarzschild spacetime ~with the Unruh vacuum! and that of ~ii! a uniformly accelerated source with the same proper acceleration in Minkowski spacetime ~with the Minkowski vacuum! are equal. We show that this equality will not hold if the Unruh vacuum is replaced by the Hartle...

We show that the response rate of (i) a static source interacting with Hawking radiation of massless scalar field in Schwarzschild spacetime (with the Unruh vacuum) and that of (ii) a uniformly accelerated source with the same proper acceleration in Minkowski spacetime (with the Minkowski vacuum) are equal. We show that this equality will not hold if the Unruh vacuum is replaced by the Hartle–H...
متن کاملEntropy of Schwarzschild black hole and string-black hole correspondence
The string-black hole correspondence is considered in the context of the correspondence principle proposed recently by Horowitz and Polchinski [7]. We demonstrate that the entropy of string states and the entropy of a Schwarzschild black hole can be matched including the subleading terms which depend on mass logarithmically. We argue the necessity to include the string interaction (with couplin...
متن کاملTunnelling Effect and Hawking Radiation from a Vaidya Black Hole
In this paper, we extend Parikh’ work to the non-stationary black hole. As an example of the non-stationary black hole, we study the tunnelling effect and Hawking radiation from a Vaidya black hole whose Bondi mass is identical to its mass parameter. We view Hawking radiation as a tunnelling process across the event horizon and calculate the tunnelling probability. We find that the result is di...
متن کاملSchwarzschild black hole with a single exterior : How thermal is the Hawking radiation ?
Several approaches to Hawking radiation on the Schwarzschild spacetime rely in some way or another on the fact that the Kruskal manifold has two causally disconnected exterior regions. To assess the physical input implied by the presence of the second exterior region, we investigate the Hawking(-Unruh) effect for a real scalar field on the RP geon: an inextendible, globally hyperbolic, space an...
