The homogeneous inviscid Burgers equation, which determines the spectrum of a \(T\overline T \) deformed model, has a natural interpretation as the condition of the gauge invariance of the target space-time energy and momentum of a (non-critical) string theory quantised in a generalised uniform light-cone gauge which depends on the deformation parameter. As a simple application of the light-cone gauge interpretation, we derive the \(T\overline T \) deformed Lagrangian for a system of any number of scalars, fermions and chiral bosons with an arbitrary potential. We find that the \(T\overline T \) deformation is driven by the canonical Noether stress-energy tensor but not the covariant one.

$$ T \ overline T $$ T T的变形和光锥仪

确定\（T \ overline T \）变形模型频谱的齐次无粘Burgers方程具有自然的解释，即目标时空能量和动量（非临界）的量规不变性的条件弦理论在广义的均匀圆锥形量规中量化，该量规取决于变形参数。作为光锥量规解释的简单应用，我们推导了（T \ overline T \）变形拉格朗日数，该系统具有任意数量的标量，费米子和手性玻色子，并且具有任意势。我们发现\（T \ overline T \）变形是由规范的Noether应力-能量张量驱动的，而不是协变量。
