  1. 1. The black hole information paradox and holography

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Ona Mola Bertran; [2023]
    Keywords : information paradox; semiclassical physics; holography; AdS CFT correspondence; island formula; entanglement entropy;

    Abstract : 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

  3. 2. Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Duncan Jones; [2023]
    Keywords : Geography; Geographical Information Systems; GIS; Habitat Modelling; Harbour Porpoise; MaxEnt; Tidal Processes; Conservation; Earth and Environmental Sciences;

    Abstract : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur.

  4. 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 omorganisation

    Author : Eivind Hilmen Jørstad; [2021]
    Keywords : Black Holes; Hawking Radiation; Entanglement Entropy; Black Hole Information Paradox; Dilaton Gravity; Quasiparticles; Physics and Astronomy;

    Abstract : 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

  5. 4. On the Entropy of Jets

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Eivind Hilmen Jørstad; [2020]
    Keywords : Entropy; Jets; QCD; Gravity; Physics and Astronomy;

    Abstract : High energy particle collisions often produce large numbers of partons in the final state, which are clustered together in collimated sprays called jets. A recent paper [1] introduces the concept of jet entropy, which is an observable that quantifies the entanglement between the resolved and unresolved parts of a jet. READ MORE
