论文摘要
在过去的几年中,已经对均衡的综合场理论的非相关性极限进行了深入研究。最简单的非平凡情况将Sinh-Gordon模型与Lieb-Liniger模型联系起来。在这里,我们研究了平衡的非相关性极限,即在量子淬灭后的时间演化中。获得的结果与Lieb-Liniger模型的已知结果一致,因此表明非相关性极限适用于此不平衡设置。
The non-relativistic limit of integrable field theories at equilibrium has been intensively studied in the previous years; the simplest non-trivial case relates the sinh-Gordon model to the Lieb-Liniger model. Here we study this non-relativistic limit out of equilibrium, namely in the time evolution after a quantum quench. The obtained results agree with the known ones for the Lieb-Liniger model, thus showing that the non-relativistic limit is applicable in this out-of-equilibrium setting.
