The Helical Liquid and the Edge of Quantum Spin Hall Systems
Congjun Wu, B. Andrei Bernevig, Shou-Cheng Zhang
The edge states of the recently proposed quantum spin Hall systems constitute a new symmetry class of one-dimensional liquids dubbed the ``helical liquid'', where the spin orientat…
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…
Spin-orbit coupling induced magnetism in the -density wave phase of LaBaCuO superconductors
Congjun Wu, Jan Zaanen, Shou-Cheng Zhang
We study the effects of spin-orbit coupling in the -density wave (DDW) phase. In the low-temperature orthorhombic phase of LaBaCuO, we find that spin-orbit coupl…
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…
