Exactly Solvable Points and Symmetry Protected Topological Phases of Quantum Spins on a Zig-Zag Lattice
A large number of symmetry-protected topological (SPT) phases have been hypothesized for strongly interacting spin-1=2 systems in one dimension. Realizing these SPT phases, however, often demands finetuningshardtoreachexperimentally.Andthelackofanalyticalsolutionshinderstheunderstandingoftheir many-body wave functions. Here we show that two kinds of SPT phases naturally arise for ultracold polar molecules confined in a zigzag optical lattice. This system, motivated by recent experiments, is...[Show more]
