论文摘要
我们通过在d-instanton背景的静态度量标准进行标准的Lorentz转换来获得旋转核物质的双重度度量。然后，我们研究角速度，激体密度和温度对重夸克电势的影响。结果表明，角速度和温度促进了夸克 - 易夸克对的解离，而激体密度抑制了解离。同样，根据喷射淬火参数的结果，我们发现射流淬灭参数随角速度，激数密度和温度的增加而增加，并且旋转D-instanton背景中的喷射淬灭参数大于n = 4 Sym理论的射流参数。
We get the dual gravity metric of the rotating nuclear matter by performing a standard Lorentz transformation on the static metric in the D-instanton background. Then, we study the effects of the angular velocity, the instanton density and the temperature on the heavy quark potential. It is shown that the angular velocity and the temperature promote dissociation of the quark-antiquark pair, and the instanton density suppresses dissociation. Similarly, according to the result of the jet quenching parameter, we found that the jet quenching parameter increases with the increase of angular velocity, instanton density and temperature, and the jet quenching parameter in the rotating D-instanton background is larger than that of N = 4 SYM theory.
