3614. (I) Understanding the Quark Gluon Plasma using High-Performance Computing and Bayesian Analyses

Prof. Gojko Vujanovic (University of Regina)

21/06/2023, 13:45

Theoretical Physics / Physique théorique (DTP-DPT)

Invited Speaker / Conférencier(ère) invité(e)

Constraining the properties of nuclear media at extreme densities has been a long-time goal of relativistic heavy-ion collision experiments. Mounting evidence gathered from these experiments suggests that a strongly interacting plasma of quarks and gluons – the Quark Gluon Plasma (QGP) – is being created within these collisions. The QGP can be well described using multi-stage simulations where...

3832. Gravitational Effect on Quark Gluon Plasma

Dr Arundhati Dasgupta (University of Lethbridge)

21/06/2023, 14:15

Theoretical Physics / Physique théorique (DTP-DPT)

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

We discuss how a condensate of non-abelian gauge fields is impacted with gravitational interactions in the early universe. The aim is to provide for new observational physics in the current cosmological background, as relics of early universe phenomena.

3652. (G*) Unified Interacting Quark Stars in 4D Gauss-Bonnet Gravity

Michael Gammon (University of Waterloo)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Since the derivation of a well-defined D → 4 limit for 4D Gauss-Bonnet (4DGB) gravity coupled to a scalar field, there has been interest in testing it as an alternative to Einstein’s general theory of relativity. Using the Tolman-Oppenheimer-Volkoff (TOV) equations modified for 4DGB gravity, we model the stellar structure of quark stars (QS) using a novel interacting quark matter equation of...

3651. Mutual information harvested by uniformly accelerated particle detectors

Theoretical Physics / Physique théorique (DTP-DPT)

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

We investigate the mutual information harvesting protocol for two uniformly accelerated particle detectors. We numerically show that, while a single detector responds as if it is immersed in a thermal bath, the quantum mutual information between two accelerating detectors behaves differently than that of two inertial detectors in a thermal bath. This is due to the fact that while the Wightman...

3887. (G*) A Complex Window-Based Joint-Chirp-Rate-Time-Frequency Transform for BBH Merger Gravitational Wave Signal Detection

Xiyuan Li (Department of Physics and Astronomy, University of Western Ontario)

21/06/2023, 15:00

Theoretical Physics / Physique théorique (DTP-DPT)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Low-latency detection of Binary Black Hole (BBH) and Binary Neutron Star (BNS) merger Gravitational Wave (GW) signals is essential for enabling multi-messenger observations of such systems. The merger GW signals have changing frequencies and are contaminated by non-stationary noises. Earlier studies of non-templated merger signal detection techniques used traditional Fourier transform-based...
