Ahn, Doyeol, Journal of high energy physics : JHEP v.2007 no.3 , 2007, pp.021 – 021 10.1088/1126-6708/2007/03/021 Contradiction between Hawking’s semi-classical arguments and the string theory on the evaporation of a black hole has been one of the most intriguing problems in fundamental physics. A final-state boundary condition inside the black hole was proposed by Horowitz and Maldacena to resolve this contradiction. We point out that the original Hawking effect can also be regarded as a separate boundary condition at the event horizon for this scenario. Here, we found that the change of the Hawking boundary condition may affect the information transfer …

Ahn, D. Physics letters: Av.366 no.3 , 2007, pp.202 – 205  10.1016/j.physleta.2007.01.072 We consider the system of free scalar field, which is assumed to be a two-mode squeezed state from an inertial point of view. This setting allows the use of entanglement measure for continuous variables, which can be applied to discuss free and bound entanglement from the point of view from non-inertial observer.
