It is intended to calculate transport properties as viscosity or heat conductivity for quantum field theories with strong interactions. The results serve as input for hydrodynamical simulations which are used to describe current heavy ion experiments (for example at RHIC or at the LHC). The functional renormalization group method will also be used to investigate the universality of transport coefficients. A conjecture recently obtained with string theory methods which predicts that quantum fluctuations lead to a lower bound for the ratio of shear viscosity and entropy density, shall be tested.

它的目的是计算具有强相互作用的量子场论的输运性质，如粘性或热导率。这些结果作为流体动力学模拟的输入，用于描述当前的重离子实验(例如，在RHIC或在LHC)。泛函重整化群方法也将被用来研究输运系数的普适性。最近用弦理论方法得到的一个猜想，即量子涨落导致切变粘度与熵密度之比的下限，将受到检验。
