摘要：

Chiral condensates in the trivial light-cone vacuum emerge if defined as short-time limits of fermion propagators. In gauge theories, the necessary inclusion of a gauge string in combination with the characteristic light-cone infrared singularities contain the relevant nonperturbative ingredients responsible for the formation of the condensate, as demonstrated for the 't Hooft model.
