The focus of our joint investigations is the diagnostics of high energy density matter. A key quantity is the dynamical (optical) conductivity that is measured in the static case, but also in optical spectroscopy, reflectivity measurements, absorption and related phenomena, in addition to thermodynamic properties. It can be calculated via the dielectric function with modern quantum-statistical methods (Green's function techniques, response formalism, numerical simulations) by the applicants in Rostock.In Chernogolovka, the Russian partners provide a broad spectrum of experimental methods (chemical explosions in different geometries) to create and analyze strongly correlated plasmas by shock waves. In these experiments, they obtain the Hugoniot curve, as well as the electrical conductivity, Hall resistivity, optical spectra and reflectivity as a function of pressure and temperature. In connection with the proposed project, new shock wave experiments shall be carried out and interpreted with the help of theoretical models. The problem of the metal-insulator transition (plasma phase transition), the determination of the equation of state and diagnostics by spectral line shapes are firmly connected to the project. In the experiments, dense nobel gases (helium, argon and xenon) will be used as target materials.

我们联合调查的重点是高能量密度物质的诊断。一个关键的量是动态（光学）电导率，在静态情况下测量，但也在光谱学，反射率测量，吸收和相关现象，除了热力学性质。它可以由罗斯托克的申请人用现代量子统计方法（绿色函数技术、响应形式主义、数值模拟）通过介电函数计算。在切尔诺戈洛夫卡，俄罗斯合作伙伴提供了广泛的实验方法（不同几何形状的化学爆炸），通过冲击波产生和分析强相关等离子体。在这些实验中，他们获得了Hugoniot曲线，以及电导率，霍尔电阻率，光谱和反射率作为压力和温度的函数。在拟议项目方面，应进行新的冲击波实验，并借助理论模型进行解释。金属-绝缘体转变（等离子体相变）的问题，状态方程的确定和光谱线形状的诊断都与该项目密切相关。在实验中，将使用致密的诺贝尔气体（氦、氩和氙）作为靶材料。
