论文摘要
我们在这里提出MSSPEC介电函数模块（MSSPEC-DFM），该模块在电子气体或液体中生成介电函数，或分离或嵌入到环境中。除了标准模型（例如等离子体杆和RPA）外，该模块还提供了更多涉及的方法（以说明相关性），Boltzmann-Vlasov流体动力学方法，放松抑制的Mermin和扩散抑制的Hu-O'Conconnell方法，以及使用NEVAN的功能或NEVAN的功能。最终，通过使用形式因素，MSSPEC-DFM模块将能够解决多种材料，例如金属，半导体，包括反转层，异方差，超导体，超导体，量子井，量子井，量子孔，量子点，等狄拉克材料，例如石墨烯和液体。
We present here the MsSpec Dielectric Function module (MsSpec-DFM), which generates dielectric functions in an electron gas or a liquid, either isolated or embedded into an environment. In addition to standard models such as the plasmon pole and the RPA, this module also provides more involved methods incorporating local field corrections (in order to account for correlations), Boltzmann-Vlasov hydrodynamical methods, the relaxation-damped Mermin and the diffusion-damped Hu-O'Connell methods, as well as moment-based methods using either a Nevanlinna function or a memory function. Ultimately, through the use of form factors, the MsSpec-DFM module will be able to address a wide range of materials such as metals, semiconductors, including inversion layers, hetero-structures, superconductors, quantum wells, quantum wires, quantum dots, Dirac materials such as graphene, and liquids.
