Entanglement entropy, fidelity and the phase transition of one-dimensional hard-core bosonic system with three-body interactions
Jie Ren, Tao Wang, Xue-Fen Xu +1
We study the one-dimensional hard-core Bose-Hubbard model with three-body interactions. In previous work[1], the two-thirds filling solid with both bond-wave order (BOW) and charge…

Tuning the Quantum Phase Transition of Bosons in Optical Lattices via Periodic Modulation of s-Wave Scattering Length
Tao Wang, Xue-Feng Zhang, Francisco Ednilson Alves dos Santos +2
We consider interacting bosons in a 2D square and a 3D cubic optical lattice with a periodic modulation of the s-wave scattering length. At first we map the underlying periodically…
