We revisit a non-perturbative formulation leading to a vacuum-created gravitational pair of (33̄)$(3\bar {3})$-brane by a Poincare dual higher form U(1) gauge theory on a D4-brane. In particular, the analysis has revealed a dynamical geometric torsion ℋ3$\mathcal {H}_{3}$ for an onshell Neveu-Schwarz (NS) form on a fat 4-brane. We argue that a D-instanton can be a viable candidate to incorporate the quintessence correction hidden to an emergent (3 + 1)-dimensional brane universe. It is shown that a dynamical non-perturbative correction may be realized with an axionic scalar QFT on an emergent anti-3-brane within a gravitational pair. The theoretical tool provokes thought to believe for an extra instantaneous dimension transverse to our classical brane-universe in an emergent scenario. Interestingly a D-instanton correction, sourced by an axion on an anti-3-brane, may serve as a potential candidate to explain the accelerated rate of expansion of our 3-brane universe and may provide a clue to the origin of dark energy.

紧急 D-Instanton 作为暗能量的来源

我们通过在 D4-膜上的庞加莱双高形式 U(1) 规范理论重新审视了一个非微扰公式，导致真空产生的 (33̄)$(3\bar{3})$-膜引力对。特别是，该分析揭示了脂肪 4 膜上的壳内 Neveu-Schwarz (NS) 形式的动力学几何扭转 ℋ3$\mathcal {H}_{3}$。我们认为 D-instanton 可以是一个可行的候选者，可以将隐藏在涌现 (3 + 1) 维膜宇宙中的精髓校正合并。结果表明，在引力对内的涌现反 3-膜上，可以使用轴离子标量 QFT 实现动态非微扰校正。该理论工具引发了人们的思考，认为在紧急情况下会存在横向于我们的经典膜宇宙的额外瞬时维度。有趣的是 D-instanton 校正，
