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…
