非局部理论的局部化

Localization of nonlocal theories

Gianluca Calcagni, Michele Montobbio, Giuseppe Nardelli

摘要:

我们证明了一类非定域标量模型,与动力学运营商的启发弦场论,相当于一个系统,这是本地的坐标,但非本地的辅助演化变量。这个系统承认拉格朗日和哈密顿公式,它的柯西问题和量子化是定义良好的。我们分类精确的非微扰解的本地化模型,可以通过扩散方程管理的领域。

英文摘要:

We show that a certain class of nonlocal scalar models, with a kinetic operator inspired by string field theory, is equivalent to a system which is local in the coordinates but nonlocal in an auxiliary evolution variable. This system admits both Lagrangian and Hamiltonian formulations, and its Cauchy problem and quantization are well-defined. We classify exact nonperturbative solutions of the localized model which can be found via the diffusion equation governing the fields.
