长程场论中的量子猝灭

Quantum quench in long-range field theories

M. A. Rajabpour, S. Sotiriadis

摘要:

研究了在$3$和$d=1,2$维中质量猝灭后长程场论中观测量的平衡性质。我们分类的制度,我们期望在不同的维度平衡或其缺乏。此外,我们还研究了初态对系统平衡性质的影响。在自由场论的情况下,我们表明,只要我们有平衡的长期限制的相关性可以描述的广义吉布斯包络。证明了系统中所有运动积分都是非局部的。

英文摘要:

We study equilibration properties of observables in long-range field theories after the mass quench in $d=1,2$ and $3$ dimensions. We classify the regimes where we expect equilibration or its absence in different dimensions. In addition we study the effect of the initial state in the equilibration properties of our system. In the case of free field theories we show that whenever we have equilibration the long-time limit of correlations can be described by the Generalized Gibbs Ensemble. We prove that all integrals of motions in our system are non-local.
