摘要:

本文综述了基于爱因斯坦引力的5维全息模型。这样的理论,为明智的选择潜力是非常接近的物理学的大N YM理论在零和有限的温度。零温胶球谱以及它们的有限温度热力学函数与晶格数据进行了比较。该模型可用于计算与夸克-胶子等离子体物理有关的输运系数,如体粘滞系数、曳力和喷流猝灭参数。

英文摘要:

We provide a review to holographic models based on Einstein-dilaton gravity with a potential in 5 dimensions. Such theories, for a judicious choice of potential are very close to the physics of large-N YM theory both at zero and finite temperature. The zero temperature glueball spectra as well as their finite temperature thermodynamic functions compare well with lattice data. The model can be used to calculate transport coefficients, like bulk viscosity, the drag force and jet quenching parameters, relevant for the physics of the Quark-Gluon Plasma.
