| Non-equilibrium evolution of in-medium bottomonium states in an open quantum system approach |
| Speaker: | Michael Strickland (Kent State University) |
| Abstract: | I will present recent work that aims to provide a more comprehensive and systematic understanding of bottomonium dynamics in the quark-gluon plasma using an open quantum system (OQS) approach that is applied in the framework of the potential non-relativistic QCD (pNRQCD) effective field theory. I will review how the computation of bottomonium suppression can be reduced to solving a Gorini-Kossakowski-Sudarshan-Lindblad (GKSL) equation for the evolution of the b-bbar reduced density matrix, which includes both singlet and octet configurations plus medium-induced transitions between them. The formalism obtained is accurate at next-to-leading order (NLO) in the binding energy over temperature. I then discuss how the NLO GKSL equation can be coupled to state-of-the-art 3+1D dissipative hydrodynamics codes in order to make phenomenological predictions.

| Learning Trivializing Gradient Flows |
| Speaker: | Simone Bacchio (Computation-based Science and Technology Research Center, The Cyprus Institute, Nicosia, Cyprus) |
| Abstract: | In our recent work, [arXiv:2212.08469][1], we have presented a new approach for trivializing flows that starts from the perturbative construction of trivializing maps by Lüscher and improves on it by learning. The resulting continuous normalizing flow model can be implemented using common tools of lattice field theory and requires several orders of magnitude fewer parameters than state-of-the-art deep learning approaches. Specifically, our model can achieve competitive performance with as few as 14 parameters while existing deep-learning models have around 1 million parameters for SU(3). |
