该研究扩展弦论中的D3-反D3膜暴胀模型为双对形式，发现其湮灭产生的介电3膜可作为原初黑洞种子，为原初黑洞起源提供了新的弦论视角。
AI 中文摘要
弦论中成功的D3-反D3膜暴胀模型的自然扩展是包含两对D3-反D3膜的模型，这在弦论中产生了新特征。当第一对膜湮灭时，会产生D1弦和F1弦。根据弦论中的非对易几何性质，Myers表明，剩余D3-反D3膜对的D3荷场强的存在会导致介电3膜的形成——即3膜与D1弦组成的中性有限大小束缚态。这些介电3膜表现为压强很小或无压强的物质，质量跨度很广，可在早期宇宙中作为原初黑洞的种子。
英文摘要
A natural extension of the successful $D3$-${\bar D}3$-brane inflation model in string theory is one with two $D3$-${\bar D}3$-brane pairs, giving rise to a novel feature in string-theory. When the first pair annihilates, $D1$-strings and $F1$-strings are produced. Following the non-commutative geometric properties in string theory, it is shown by Myers that the presence of the $D3$-charge field strength of the remaining $D3$-${\bar D}3$-brane pair leads to the formation of dielectric $3$-branes -- neutral, finite-size bound states of $3$-branes with $D1$-strings. They behave as matter with little or no pressure. Spanning a wide range of masses, they seed primordial black holes in the early universe.
