论文摘要
我们在增强框架中研究哈密顿截断。我们考虑使用有限动量下使用TCSA的2D ISING模型的热和磁场变形。我们发现,即使使用中等动量,频谱和时间依赖性的相关函数也会显着依赖于系统的体积。这允许更可靠地确定无限的体积可观察物。
We study Hamiltonian truncation in boosted frames. We consider the thermal and magnetic field deformations of the 2d Ising model using TCSA at finite momentum. We find that even with moderate momenta, the spectrum and time-dependent correlation functions become significantly less dependent on the volume of the system. This allows for a more reliable determination of infinite volume observables.
