Emergence of Large-Scale Structures in Holographic Superfluid Turbulence
arxiv(2024)
摘要
In two-dimensional turbulence systems, the emergence of large-scale
structures holds profound physical implications, particularly as it indicates
the occurrence of inverse energy cascades, thereby garnering significant
attention. In this paper, we report a novel vortex clusters formation in the
background of near-extreme Reissner-Nordström black hole holographic
model. At temperatures nearing absolute zero, we observe not only the formation
of vortex clusters but also the emergence of an inverse energy cascade.
Distinct from typical quantum systems, the genesis of holographic vortex
clusters is rooted in unique quantum dissipation properties, characterized by
the near immobilization of vortex dipoles at low temperatures. Through a
comparative analysis with the dynamics of the Gross-Pitaevskii equation, our
investigation enhances the understanding of inverse energy cascades under these
extreme conditions, thereby broadening our comprehension of quantum turbulence.
