在半平地上解开琴弦
Unwinding strings in semi-flatland
摘要：
研究了非零缠绕数弦在T-对偶缺陷周围的动力学行为。我们推断，这样的非几何对象的核心附近的物理涉及的缠绕模式，不被捕获的超引力近似，我们认为，这样的修正是T-对偶的模式负责半平坦的椭圆度量的量子修正。此外，我们构建了一个解决方案的双场论，捕捉这样的近核物理的一部分。
英文摘要：
We study the dynamics of strings with non-zero winding number around T-duality defects. We deduce that the physics near the core of such non-geometric objects involves winding modes that are not captured by the supergravity approximation, and we argue that such corrections are T-dual to the modes responsible for quantum corrections of semi-flat elliptic metrics. We furthermore construct a solution of double field theory that captures part of such near-core physics.
