Frustrated planepolarized dipoles in one dimension
Abstract
We investigate the zerotemperature quantum phases of a quasionedimensional zigzag chain of dipoles that are polarized in a plane by an external electric field. Since the Hamiltonian contains nearestneighbor and nextnearestneighbor hopping and interaction terms, this model allows frustration, which induces phases that can be interesting and unusual. By using the density matrix renormalization group algorithm, we produce a complex phase diagram. This is an extension of an earlier work by Wang et al. [Phys. Rev. A 96, 043615 (2017), 10.1103/PhysRevA.96.043615].
