Phase diagram of a generalized off-diagonal Aubry–André model with<i>p</i>-wave pairing
Off-diagonal Aubry-André (AA) model has recently attracted a great deal of attention as they provide condensed matter realization of topological phases.We numerically study a generalized off-diagonal AA model with p-wave superfluid pairing in the presence of both commensurate and incommensurate hopping modulations.The phase diagram as functions of the modulation strength …
