Spontaneous plaquette formation in the SU(4) Spin-Orbital ladder
M. van den Bossche, P. Azaria, P. Lecheminant +1
The low-energy properties of the SU(4) spin-orbital model on a two-leg ladder are studied by a variety of analytical and numerical techniques. Like in the case of SU(2) models, the…

Plaquette Ground State in the Two-dimensional SU(4) Spin-Orbital Model
Mathias van den Bossche, Fu-Chun Zhang, Frederic Mila
In order to understand the properties of Mott insulators with strong ground state orbital fluctuations, we study the zero temperature properties of the SU(4) spin-orbital model on…
