Jaume Gomis, Ziqi Yan, Matthew Yu

摘要:

构造了描述任意非相对论性开弦和闭弦背景下的非相对论性开弦论的经典和量子世界片理论。我们证明了在平坦时空中终止于n个重合D-膜上的开弦的低能动力学可用伽利略不变量U(n)Yang-Mills理论描述。我们还研究了非相对论性开弦激发与缠绕数,并证明其动力学可以编码成一个本地规范理论在一个更高的维度。通过要求边界耦合的共形不变性,非线性运动方程,管理一致的开放弦背景耦合到一个任意的封闭的背景(描述的弦牛顿-Cartan几何,Kalb-Ramond,和Escherton场)推导和出现从伽利略不变的Dirac-Born-Infeld型作用。

英文摘要:

The classical and quantum worldsheet theory describing nonrelativistic open string theory in an arbitrary nonrelativistic open and closed string background is constructed. We show that the low energy dynamics of open strings ending on n coincident D-branes in flat spacetime is described by a Galilean invariant U(n) Yang-Mills theory. We also study nonrelativistic open string excitations with winding number and demonstrate that their dynamics can be encoded into a local gauge theory in one higher dimension. By demanding conformal invariance of the boundary couplings, the nonlinear equations of motion that govern the consistent open string backgrounds coupled to an arbitrary closed background (described by a string Newton-Cartan geometry, Kalb-Ramond, and dilaton field) are derived and shown to emerge from a Galilean invariant Dirac-Born-Infeld type action.
