  1. 3773. Multicritical Black Holes

    Oral (Non-Student) / Orale (non-étudiant(e))

    The inclusion of thermodynamic pressure has been one of the major developments in black hole thermodynamics in recent years. By incorporating pressure, black holes are now known to exhibit behaviour corresponding to that seen in a broad variety of chemical systems, including liquid-gas type transitions, reentrant phase behaviour, polymer-like transitions, superfluid phase behaviour, and...

  2. 3896. (G*) Rotational Effects on Fisher Information of Thermal Black Hole Parameter
    Everett Patterson (University of Waterloo)

    Theoretical Physics / Physique théorique (DTP-DPT)
    Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

    Relativistic quantum metrology is a framework that not only accounts for both relativistic and quantum effects when performing measurements and estimations, but further improves upon classical estimation protocols by exploiting quantum relativistic properties of a given system.
    Here I present recent developments in the Fisher information analysis associated with black hole spacetimes. I...

  3. 3765. How do black hole horizons interact with the rest of the universe?

    Oral (Non-Student) / Orale (non-étudiant(e))

    During simulations of a binary black hole collision, the final (post-merger) black hole horizon exhibits a decaying oscillation. There is also an observable gravitational wave signal from this black hole ringdown. Then it is natural to think that the oscillation generates the gravitational wave signal. However, this is not the case. By definition the black hole horizon (either event or...

  4. 3677. A classical-quantum approximation for bipartite quantum systems
    Sanjeev Seahra (University of New Brunswick)

    Theoretical Physics / Physique théorique (DTP-DPT)
    Oral (Non-Student) / Orale (non-étudiant(e))

    We derive a "classical-quantum" approximation scheme for a broad class of bipartite quantum systems. In this approximation, one subsystem's evolution is governed by classical equations of motion with quantum corrections, and the other subsystem evolves quantum mechanically with equations of motion informed by the classical degrees of freedom. Similar approximations are common when...

  5. 3587. New symplectic formalism for spacetimes with marginally outer trapped tubes
    Juan Margalef (Memorial University)
    20/06/2023, 09:30
    Theoretical Physics / Physique théorique (DTP-DPT)
    Oral (Non-Student) / Orale (non-étudiant(e))

    Marginally outer trapped tubes are one of the essential tools to understand the dynamical evolution of Black Holes. In this talk, I will present a new symplectic formalism that applies to various spacetimes containing a BH. This framework allows studying charges, flux laws, and higher multiple moments. All this is directly linked to the study of gravitational waves.
