具有动态规范场的全息d膜结构
近日,上海交通大学Yong jun Ahn团队研究了具有动态规范场的全息d膜结构。这一研究成果于2026年3月12日发表在《高能物理杂志》上。
全息D膜构建由狄拉克-博恩-因费尔德(DBI)作用量支配,在AdS/CFT对偶中扮演核心角色,尤其在量子色动力学和凝聚态系统的应用中。
在这项工作中,研究组展示了如何为这些自上而下的全息模型配备动力学边界规范场,从而将电磁相互作用引入其对偶场论描述中。作为这一形式体系的直接应用,研究组计算了平衡态与非平衡稳态下最低准正规模式的色散关系,并证明其行为符合具有动力学U(1)对称性的流体力学预测。

Abstract: Holographic D-brane constructions, governed by the Dirac-Born-Infeld (DBI) action, play a central role in the AdS/CFT correspondence, particularly in applications to quantum chromodynamics and condensed matter systems. In this work, we demonstrate how to equip these bottom-up holographic models with dynamical boundary gauge fields, thereby introducing electromagnetic interactions into their dual field theory descriptions. As a direct application of this formalism, we compute the dispersion relations of the lowest quasinormal modes around both equilibrium and nonequilibrium steady states, and show that their behavior matches the predictions from hydrodynamics with dynamical U(1) symmetry.
