    WITS Node Seminar: Dr Joey Medved (Rhodes University)

    The National Institute for Theoretical Physics, and the Centre for Theoretical Physics, School of Physics, would like to invite to its coming talk in the theoretical physics seminar series, entitled:

    "Semiclassical Black Holes: A Prescription for its Paradoxes"

    to be presented by Dr. Joey Medved (Rhodes University)

    Abstract: Soon after Stephen Hawking had demonstrated that semiclassical black holes emit radiation, a number of interesting paradoxes came to light. For instance, black hole evaporation seems to imply the apparent loss of information and the non-existence of global conserved charges, in direct conflict with the tenants of quantum field theory (on which the Hawking calculation is based). In spite of the years of debate over such issues (now brought to the forefront by the recent ''firewall'' controversy), there is a remarkably simple resolution that has been previously overlooked. The answer lies in (the so far neglected) quantum fluctuations of the background geometry. I will talk about recent work along this lines.

    Date: Tuesday, 28th May 2013
    Venue: Frank Nabarro Lecture Theatre P216
    Time: 13.20 - 14.10

    I hope you shall all be able to attend,

    Yours sincerely,
