Prof. Mark Alford (Washington University in St. Louis)
I will describe what the standard model leads us to expect for the densest phase of matter: quark matter. Quark matter is predicted to have a rich phase structure, including color superconductors, superfluids, insulators, and crystals. Quark matter may exist in nature, formed in the ultra-compressed cores of neutron stars: I will review the search for signatures of its presence.
Prof. David Mateos (ICREA & U of Barcelona)
A massive experimental effort will be devoted in the coming years to the physics of QCD at high energy density and/or high baryon density. Understanding this physics, especially out of equilibrium, is an important theoretical challenge. I will discuss how holography can help us address this challenge. Topics covered will include the far-from-equilibrium dynamics near the QCD critical point and...
Prof. Paulo Bedaque (University of Maryland College Park)
We will discuss a programme to circumvent the ``sign problem" in lattice calculations in field theory. The main idea is to deform the region of integration in field space to the complex domain. The theoretical underpinnings and algorithms will be exemplified through the application of the method to low dimensional finite density models and real time calculations.
Prof. Mikhail Stephanov (UIC)
The search for the QCD critical point in heavy-ion collision experiments requires dynamical modeling of the bulk evolution of the QCD matter as well as of the fluctuations near the critical point. Critical slowing down means that fluctuations are significantly deviating from equilibrium near the critical point. We generalize hydrodynamics to quasi-equilibrium conditions where the state of...
Prof. Nils Andersson (University of Southampton)
Gravitational waves may drive the oscillations of a rotating neutron star unstable. In turn, the angular momentum carried away by the waves would spin the star down. This mechanism may determine the spin evolution of newly born neutron stars. It may also set a speed limit for neutron stars that accrete matter (and gain angular momentum) from a binary companion. In this talk I will provide an...
Prof. Luciano Rezzolla (University of Frankfurt)
I will discuss the rapid recent progress made in modelling neutron stars in binary system and show how the inspiral and merger of these systems is more than a strong source of gravitational waves. Indeed, while the gravitational signal can provide tight constraints on the equation of state for matter at nuclear densities, the formation of a black-hole--torus system can explain much of the...
Dr Alfredo Urbano (INFN, sez. di Trieste and CERN)
Axions are ubiquitous in beyond the Standard Model theories, ranging from ordinary QCD to exotic string theory constructions. In this talk, I will present and discuss -- both from a theoretical and a phenomenological viewpoint -- their rich interplay with General Relativity in relation with gravitational wave astrophysics and cosmology.
Stephan Huber (University of Sussex)
I will discuss phase transitions at the TeV scale, in particular the electroweak one (in extensions of the standard model). I will review the current status of how gravitational waves are generated during the phase transition, and show how the resulting gravitational wave signal can be computed from key properties of the transition. Finally, I will discuss detection prospects at future...
Tyler Gorda (University of Helsinki)
The LIGO/Virgo detection of gravitational waves originating from a neutron-star (NS) merger, GW170817, has recently provided new stringent limits on the tidal deformabilities of the stars involved in the collision. In this talk, I will discuss recent analysis of the implications of this measurement for the NS-matter equation of state (EoS). In our analysis, we combinine this measurement with...
Dr Jan Fiete Grosse-Oetringhaus (CERN)
I will review the latest experimental results of heavy-ion physics, focussing on results from the Large Hadron Collider (LHC) and the Relativistic Heavy-Ion Collider (RHIC). A particular emphasis is given on the topic of collectivity in small systems, i.e. the paradigm-shifting observation that experimental signatures traditionally associated with the production of a large and deconfined...
Prof. Paul Romatschke (University of Colorado Boulder)
Having a thermalized system is the textbook requirement for the applicability of hydrodynamics. However, there is mounting evidence that hydrodynamics offers a good quantitative description even in off-equilibrium situations. Recent applications of resurgence to relativistic fluid dynamics in the context of conformal systems is able to put the new, generalized theory of off-equilibrium...
Konrad Tywoniuk (CERN)
Hard processes in heavy-ion collisions, in particular those involving the production of jets in the final-state, can potentially serve as well-constrained probes of a hot and dense QCD medium. At high-energies, radiation stimulated via interactions with the medium, that is subject to LPM interference effects, control the amount of energy radiated away from the jet constituents, providing a...
Dr Jacopo Ghiglieri (CERN)
I will give an overview of the determination of the transport coefficients of QCD at next-to-leading order. It is known that leading-order perturbative computations give values of the shear viscosity over entropy density ($\eta/s$) that are significantly larger than phenomenological values and AdS/CFT computations. I will thus explain the recent improvements in our understanding of thermal...
Peter Arnold (University of Virginia)
High-energy particles passing through matter lose energy by showering via splitting processes such as hard bremsstrahlung and pair production. There has been a great deal of research in the last 5 years on what happens if two successive splittings in such a shower overlap quantum mechanically, so that their splitting probabilities cannot be treated independently. The effects of soft...
Prof. Geraldine Servant (U. Hamburg and DESY)
The nature of the electroweak phase transition is still weakly constrained experimentally and many possibilities remain open, in particular when the scalar sector of the theory is extended. There has been growing interest lately in the possibility of a strong first-order electroweak phase transition, not only because of its relevance for baryogenesis but also because it is a potential source...
Dr Szabolcs Borsanyi (University of Wuppertal)
Axions are hypothetical particles that solve the strong CP problem, and contribute to the dark matter at the same time. A key input is the axion potential, that depends on the topological susceptibility in quantum chromodynamics. I discuss various lattice computations to the calculation of this quantity and its impact on the axion search.
Prof. Harvey Meyer (Johannes Gutenberg University Mainz)
We investigate the emission rate of photons in a perfectly thermalized quark-gluon plasma via lattice QCD correlation functions of the electromagnetic current. The thermal correlation functions can be split into a spatially longitudinal and a transverse part, and the photon rate is determined by the transverse part, since the longitudinal part vanishes at light-like kinematics. However,...

Heavy quarkonium related observables are very useful to obtain information about the medium created in relativistic heavy ion collisions. In recent years the theoretical description of quarkonium in a medium has moved towards a more dynamical picture in which decay and recombination processes are very important. In this talk we will discuss the equations that describe the evolution of the...
Mikko Laine (AEC, ITP, U. Bern)
There has been recent interest in leptogenesis induced by "light" right-handed neutrinos, with masses in the 1 - 100 GeV range. We review the form of rate equations applying to this system, as well as the computation of rate coefficients to leading order in Standard Model couplings. The resulting non-linear system is solved numerically, taking into account that right-handed neutrinos...
Prof. Anders Tranberg (University of Stavanger)
A strong Electroweak Phase Transition may be responsible for the observed baryon asymmetry of the Universe and may generate a detectable stochastic background of Gravitational Waves. Sadly, in the Minimal Standard Model, the transition is a weak cross-over. I will first give a short introduction to how one computes the properties of the transition perturbatively and non-perturbatively. I will...
Dr Aleksey Cherman (INT, University of Washington)
I'll review some recently-appreciated lessons from thinking about QCD and related theories on compactified directions with non-thermal boundary conditions. For example, such non-traditional compactifications sometimes allow one to define new analytically tractable regimes in gauge theory, which yield insights into the appearance of mass gaps, chiral symmetry breaking, and other dynamical phenomena.
Prof. Maciej Lewenstein (ICFO - Institut de Ciéncies Fotóniques)
I my lecture I will discuss the present status of one of the pillars of the Quantum Technologies Flagship: Quantum Simulations. I will comment on various platforms and approaches, focusing, however, on ultra-cold atoms, molecules and ions. I will present the recent progress in the most challenging quantum simulations of lattice gauge theories and speculate about the future directions, such as...
