论文摘要
在本文中,我们启动对非统一场理论中局部淬火的研究。我们在任意时空维度中考虑了大规模标量场理论中激发局部状态的动力学,并概括了众所周知的二维CFT结果。我们得出能量密度,$ u(1)$ - 电荷密度和$ ϕ^2(x)$ - 冷凝后淬火后动力学,并根据场质量和淬火正规化参数的值确定其进化的不同状态。对于高维无质量标量理论中的局部淬火,我们重现了可用全息结果的结构。我们还研究了圆柱体上大规模标量场理论中的局部淬火,并表明它们会以复杂的定位/定位模式引起可观察物的不稳定和混乱的演变。
In this paper, we initiate the study of operator local quenches in non-conformal field theories. We consider the dynamics of excited local states in massive scalar field theory in an arbitrary spacetime dimension and generalize the well-known two-dimensional CFT results. We derive the energy density, $U(1)$-charge density and $ϕ^2(x)$-condensate post-quench dynamics, and identify different regimes of their evolution depending on the values of the field mass and the quench regularization parameter. For local quenches in higher-dimensional free massless scalar theories, we reproduce the structure of the available holographic results. We also investigate the local quenches in massive scalar field theory on a cylinder and show that they cause an erratic and chaotic-like evolution of observables with a complicated localization/delocalization pattern.
