Накратко на български
Кварк-глуонната плазма, състояние на материята от ранната Вселена, се изследва чрез симулации на сблъсъци между тежки йони. Това помага да се разбере как се формира този почти идеален флуид и какви са неговите свойства.

Fast Thermalization of the Quark-Gluon Plasma
Understanding the properties of extreme phases of nuclear matter is one of the major challenges in theoretical physics. Matter under such extreme conditions was present in the very early universe - a millisecond after the big bang - and is nowadays produced in heavy ion collisions at the Relativistic Heavy Ion Collider in Brookhaven, USA and the Large Hadron Collider in Geneva, Switzerland in the form of the Quark Gluon Plasma. This extreme phase of matter is an almost perfect fluid due to its extremely low viscosity. The objectives of the project have been to elucidate how such a fluid is created and what its properties are. We have been using cutting edge numerical simulations carried out on European Supercomputers to elucidate the formation of the hot viscous plasma under controlled initial conditions. The project is an important step beyond the state-of-the-art models which assumed certain symmetries that are not present in real-life quark gluon plasmas by introducing a source that breaks these symmetries in a controlled manner. The results we find are highly exciting as they show that the creation of the plasma is very fast even in this more realistic setup. In addition they pave the way for upcoming studies of the fast creation of the Quark-Gluon plasma.

Цел на проекта
Understanding the properties of extreme phases of nuclear matter created in relativistic heavy ion collisions is one of the major challenges in theoretical physics. Matter under such extreme conditions was present in the very early universe and is nowadays produced in relativistic heavy ion collisions. In this proposal we address two questions that are central to the understanding of the very early stages of such collisions from the perspective of both strongly and weakly coupled field theory: What is the time-scale of the thermalization and why does it happen so fast?We will study these questions in the strongly coupled setup via the gauge/gravity duality by utilizing numerical relativity techniques to describe black hole formation in the gravity side. This allows to access real-time dependent non-equilibrium dynamical quantities and will improve the understanding of pre-equilibrium flow in heavy ion collisions. In order to understand thermalization at intermediate couplings we will carry out a comparison between strong and weak coupling approaches.
