| 英文摘要 | Abstract 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 of incommensurate hopping and the strength of the p-wave pairing is obtained by using the multifractal analysis. we show that with the appearance of the p-wave pairing, the system exhibits mobility-edge phases and critical phases with various number of topologically-protected zero-energy modes. predicted topological nature of these exotic phases can be realized in a cold atomic system of incommensurate bichromatic optical lattice with induced p-wave superfluid pairing by using a raman laser in proximity to a molecular bose–einstein condensation. |
