Symmetry protected topological order
Semantic Scholar uses AI to extract papers important to this topic.
In this work, we introduce a new type of topological order which is protected by subsystem symmetries which act on lower… Expand Higher-order topological insulators have a modified bulk-boundary correspondence compared to other topological phases: instead of… Expand Recent work shows that highly excited many-body localized eigenstates can exhibit broken symmetries and topological order… Expand Recently, it was realized that quantum states of matter can be classified as long-range entangled (LRE) states (i.e. with non… Expand Symmetry-protected topological (SPT) phases are gapped short-range-entangled quantum phases with a symmetry $G$, which can all be… Expand We construct an exactly soluble Hamiltonian on the D=3 cubic lattice, whose ground state is a topological phase of bosons… Expand Projected entangled pair states (PEPS) provide a natural description of the ground states of gapped, local Hamiltonians in which… Expand which equals 1 in the SPT phase, and −1 in the trivial phase. As an application of our proposal, we study the spin-1 models on… Expand Focusing on the particular case of the discrete symmetry group Z_N x Z_N, we establish a mapping between symmetry protected… Expand Topological insulators in free fermion systems have been well characterized and classified. However, it is not clear in strongly… Expand
