Charting the space of ground states with tensor networks
Marvin Qi, David T. Stephen, Xueda Wen +4
We employ matrix product states (MPS) and tensor networks to study topological properties of the space of ground states of gapped many-body systems. We focus on families of states…

Flow of (higher) Berry curvature and bulk-boundary correspondence in parametrized quantum systems
Xueda Wen, Marvin Qi, Agnès Beaudry +5
This paper is concerned with the physics of parametrized gapped quantum many-body systems, which can be viewed as a generalization of conventional topological phases of matter. In…
