  2. 13. The (glorious) past, (exciting) present and (foreseeable) future of gravitational wave detectors.

    The first trace left by a gravitational wave in a man-made detector in September 2015 marked the birth of gravitational wave astronomy. Less than four years from that first signal, gravitational wave detections have become routine, the LIGO and VIRGO instruments are standing up to their mission of being "observatories" and the trove of signals collected is enabling exciting new science and...

    I will show how quasinormal modes of black holes can be used to investigate new physics and quantum gravity. Some results on isospectrality will also be underlined.

    It is well-known that accelerating spacetimes form the basis of our understanding of early and late-time cosmology. On the other hand, there has been a pile of mounting evidence, mainly based on numerous results from String Theory (but not limited to them), that de Sitter space is difficult to embed in a quantum theory of gravity. Thus, these theoretical constraints that any consistent...

  8. 26. Quantum fluctuations of the compact phase space cosmology

    In the recent article Phys. Rev. D 100, no. 4, 043533 (2019) a compact phase space generalization of
    the flat de Sitter cosmology has been proposed. The main advantages of the compactification is that
    physical quantities are bounded, and the quantum theory is characterized by finite dimensional Hilbert
    space. The purpose of this presentation is to discuss the extraction of semiclassical...
