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…
Polaronic behavior of undoped high-Tc cuprates
O. Rösch, O. Gunnarsson, X. J. Zhou +6
We present angle-resolved photoemission spectroscopy (ARPES) data on undoped La2CuO4, indicating polaronic coupling between bosons and charge carriers. Using a shell model, we calc…
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…
