Page Curve for an Evaporating Black Hole PHYSICS A Page curve for an evaporating black hole in asymptotically flat spacetime is presented by adapting the Quantum Ryu-Takayanagi (QRT) proposal to an analytically solvable semi-classical two-dimensional dilaton gravity theory. The Page time is found to be one third of the black hole lifetime, at leading order in semi-classical corrections.

(based on arXiv:2004.00598) Larak Seminar Room 11:00 - 12:00 Theory Weekly Seminar (TWS)- Zoom Meeting Planar Maximally Entangled States School PARTICLES AND ACCELERATORS Abstract: We construct a large family of Planar Maximally Entangled (PME) states which are a wider class of multi-partite entangled states than Absolutely Maximally Entangled (AME) states. These are states in which any half of the qudits are in a maximally mixed state, provided that they form a connected subset. We show that in contrast to AMEs, PMEs are easier to find and there are various PMEs for any even number of qudits. In particular, while it is known that no AME state of four qubits exists, we show that there are two distinct multi-parameter classes of four qubit PMEs. We also give explicit families of PMEs for any even number of part ... 11:00 - 12:00 Weekly Webinar Diagnostic accuracy of different paraclinical test School BIOLOGICAL SCIENCES ... |
