Exact spontaneous plaquette ground states for high-spin ladder models
Shu Chen, Congjun Wu, Shou-Cheng Zhang +1
We study the exchange physics in high spin Mott insulating systems with which is realizable in ultracold atomic systems. The high symmetry of SO(5) or SU(4) therein renders…
Competing orders in one dimensional spin 3/2 fermionic systems
Congjun Wu
Novel competing orders are found in spin 3/2 cold atomic systems in one-dimensional optical traps and lattices. In particular, the quartetting phase, a four-fermion counterpart of…
Current Carrying Ground State in a Bi-layer Model
Sylvain Capponi, Congjun Wu, Shou-Cheng Zhang
Strongly interacting systems have been conjectured to spontaneously develop current carrying ground states under certain conditions. We conclusively demonstrate the existence of a…
Dynamic generation of spin orbit coupling
Congjun Wu, Shou-Cheng Zhang
Spin-orbit coupling plays an important role in determining the properties of solids, and is crucial for spintronics device applications. Conventional spin-orbit coupling arises mic…
Vortex configurations of bosons in an optical lattice
Congjun Wu, Han-dong Chen, Jiang-ping Hu +1
The single vortex problem in a strongly correlated bosonic system is investigated self-consistently within the mean-field theory of the Bose-Hubbard model. Near the superfluid-Mott…
Thermodynamic properties of the d-density wave order in cuprates
Congjun Wu, W. Vincent Liu
We solve a popular effective Hamiltonian of competing -density wave and d-wave superconductivity orders self-consistently at the mean-field level for a wide range of doping and…
