Sequential Quantum Circuits as Maps between Gapped Phases
Xie Chen, Arpit Dua, Michael Hermele +4
Finite-depth quantum circuits preserve the long-range entanglement structure in quantum states and map between states within a gapped phase. To map between states of different gapp…
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…
Renormalization of Ising cage-net model and generalized foliation
Zongyuan Wang, Xiuqi Ma, David T. Stephen +2
A large class of type-I fracton models, including the X-cube model, have been found to be fixed points of the foliated renormalization group (RG). The system size of such foliated…
Fractionalization of subsystem symmetries in two dimensions
David T. Stephen, Arpit Dua, José Garre-Rubio +2
The fractionalization of global symmetry charges is a striking hallmark of topological quantum order. Here, we discuss the fractionalization of subsystem symmetries in two-dimensio…
String order parameters for symmetry fractionalization in an enriched toric code
José Garre-Rubio, Mohsin Iqbal, David T. Stephen
We study a simple model of symmetry-enriched topological order obtained by decorating a toric code model with lower-dimensional symmetry-protected topological states. We show that…
Subsystem symmetry enriched topological order in three dimensions
David T. Stephen, José Garre-Rubio, Arpit Dua +1
We introduce a model of three-dimensional (3D) topological order enriched by planar subsystem symmetries. The model is constructed starting from the 3D toric code, whose ground sta…
Detecting subsystem symmetry protected topological order via entanglement entropy
David T. Stephen, Henrik Dreyer, Mohsin Iqbal +1
Subsystem symmetry protected topological (SSPT) order is a type of quantum order that is protected by symmetries acting on lower-dimensional subsystems of the entire system. In thi…
