Frustration-Induced Supersolid Phases of Extended Bose-Hubbard Model in the Hard-Core Limit
arXiv:1912.12464 · doi:10.1088/1361-648X/aba383
Abstract
We investigate exotic supersolid phases in the extended Bose-Hubbard model with infinite projected entangled-pair state, numerical exact diagonalization, and mean-field theory. We demonstrate that many different supersolid phases can be generated by changing signs of hopping terms, and the interactions along with the frustration of hopping terms are important to stabilize those supersolid states. We argue the effect of frustration introduced by the competition of hopping terms in the supersolid phases from the mean-field point of view. This helps to give a clearer picture of the background mechanism for underlying superfluid/supersolid states to be formed. With this knowledge, we predict and realize the -wave superfluid, which shares the same pairing symmetry with high- materials, and its extended phases. We believe that our results contribute to preliminary understanding for desired target phases in the real-world experimental systems.
