相对论性超流体中的流体动力学涨落

Hydrodynamic fluctuations in relativistic superfluids

Manuel A. Valle

摘要:

研究了基于非正则Poisson括号的超流体的哈密顿形式。动量密度正比于守恒能量流的假设导致了由Khalatnikov,Lebedev和Carter提出的协变相对论理论,并给出了该理论中的一些势函数。我们讨论了耗散效应存在下的流体动力学涨落,并导出了相应的流体动力学关联函数。输运系数的Kubo关系。

英文摘要:

The Hamiltonian formulation of superfluids based on noncanonical Poisson brackets is studied in detail. The assumption that the momentum density is proportional to the flow of the conserved energy is shown to lead to the covariant relativistic theory previously suggested by Khalatnikov, Lebedev and Carter, and some potentials in this theory are given explicitly. We discuss hydrodynamic fluctuations in the presence of dissipative effects and we derive the corresponding set of hydrodynamic correlation functions. Kubo relations for the transport coefficients are obtained.
