Unusual excitations and double-peak specific heat in a bond-alternating spin- - chain
Qiang Luo, Shijie Hu, Hae-Young Kee
One-dimensional gapped phases that avoid any symmetry breaking have drawn enduring attention. In this paper, we study such phases in a bond-alternating spin-1 - chain built o…
Interplay of local order and topology in the extended Haldane-Hubbard model
Can Shao, Eduardo V. Castro, Shijie Hu +1
We investigate the ground-state phase diagram of the spinful extended Haldane-Hubbard model on the honeycomb lattice using an exact-diagonalization, mean-field variational approach…
Dirac Spin Liquid on the Spin-1/2 Triangular Heisenberg Antiferromagnet
Shijie Hu, W. Zhu, Sebastian Eggert +1
We study the spin liquid candidate of the spin- - Heisenberg antiferromagnet on the triangular lattice by means of density matrix renormalization group (DMRG) simula…
Floquet-Induced Superfluidity with Periodically Modulated Interactions of Two-Species Hardcore Bosons in a One-dimensional Optical Lattice
Tao Wang, Shijie Hu, Sebastian Eggert +3
We consider two species of hard-core bosons with density dependent hopping in a one-dimensional optical lattice, for which we propose experimental realizations using time-periodic…
Ground-state phase diagram of the frustrated spin-1/2 two-leg honeycomb ladder
Qiang Luo, Shijie Hu, Jize Zhao +3
We investigate a spin- two-leg honeycomb ladder with frustrating next-nearest-neighbor (NNN) coupling along the legs, which is equivalent to two - spin chains couple…
Dynamic and thermodynamic properties of the generalised diamond chain model for azurite
Andreas Honecker, Shijie Hu, Robert Peters +1
The natural mineral azurite Cu3(CO3)2(OH)2 is an interesting spin-1/2 quantum antiferromagnet. Recently, a generalised diamond chain model has been established as a good descriptio…
