Description
We revisit the massive Schwinger model on a circle via the staggered fermion. Given the periodic boundary condition, the translation invariance is well defined on the lattice, and so is the momentum. Due to the topology, the relic zero-mode electric field is still dynamical after all others integrated out via the Gauss's law. We demonstrate how the gauge invariance, particularly the large gauge transformation, can be realized in the real-time quantum algorithms. We further illustrate on the quantum hardware the scattering of two wave-packets of vector mode, based on the strong-coupling analysis.
