标题： Real-time scattering in the lattice Schwinger model

摘要： 张量网络方法已显示出其在研究格点规范理论平衡性质方面的适用性，即使接近连续极限。我们将其用于非平衡情景，这是迄今为止探索较少的领域，通过模拟格点施温格模型中复合介子的实时碰撞。在不同入射动量下构建矢量介子的波包，我们观察到非弹性通道的开启，在该通道中产生两个更重的介子，并确定了动量阈值。为了在强耦合 regime 中检测碰撞产物，我们提出了可以在当前量子模拟平台中测量的局部量。 显示英文摘要

摘要： Tensor network methods have demonstrated their suitability for the study of equilibrium properties of lattice gauge theories, even close to the continuum limit. We use them in an out-of-equilibrium scenario, much less explored so far, by simulating the real-time collisions of composite mesons in the lattice Schwinger model. Constructing wave-packets of vector mesons at different incoming momenta, we observe the opening of the inelastic channel in which two heavier mesons are produced and identify the momentum threshold. To detect the products of the collision in the strong coupling regime we propose local quantitites that could be measured in current quantum simulation platforms.
