1. The black hole information paradox and holography
University essay from Uppsala universitet/Teoretisk fysikAbstract : Hawking theorized in 1974 that black holes emit particles as a quantum effect. It follows from this fact that a black hole that emits particles while absorbing none ends up evaporating. The process of black hole evaporation studied from semiclassical gravity violates quantum mechanics leading to serious problems. READ MORE

2. Cosmological Horizons and the Unruh Effect
University essay from Uppsala universitet/Teoretisk fysikAbstract : The black hole information paradox, which states that the evaporation of black holes due to Hawking radiation results in a violation of the conservation of quantum information, is arguably one of the most fundamental problems in all of modern physics. Through the equivalence principle, the essence of the problem can be understood and studied in the context of much simpler flat spacetime (described by the theory of special relativity); in this context the Hawking radiation takes the form of the so-called Unruh effect, a thermal effect in the vacuum of a Minkowski quantum field theory that can be measured by accelerated observers.

3. Recent Progress on the Black Hole Information Paradox
University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationAbstract : The black hole information paradox is of central importance in the study of quantum gravity. The paradox states that quantum fields surrounding a black hole behave in ways that run into conflict with the unitarity of quantum mechanical time evolution. READ MORE

4. The information paradox - Horizon structures and its effects on the quasinormal mode gravitational radiation from binary merger ringdowns : Gravitational echoes from reflective near horizon structures
University essay from Uppsala universitet/Teoretisk fysikAbstract : Classical theory cannot provide a satisfying scenario for a unitary thermodynamic evolution of black holes. To preserve information one requires quantum mechanical effects on scales reaching beyond the traditional horizon radius. READ MORE

5. Entanglement and the black hole information paradox
University essay from Uppsala universitet/Teoretisk fysikAbstract : The black hole information paradox arises when quantum mechanical effects are considered in the vicinity of the event horizon of a black hole. In this report we describe the fundamental properties of quantum mechanical systems and black holes that lead to the information paradox, with focus on quantum entanglement. READ MORE
