Penc Karlo (Wigner FK):
Spin liquid phases in the SU(4) and SU(3) Heisenberg model on the honeycomb

"SU(N) Heisenberg model is the effective model of Mott insulators with N
degrees of freedom per site, when the interaction is highly symmetrical. Such
a situation may happen for spin-orbital systems and for ultracold
alkaline-earth atoms in optical lattices. Using a combination of analytical
and numerical methods, we studied the zero temperature properties of the
model on honeycomb lattice for different values of N. In the seminar, I will
present our recent findings for the spin-orbital liquid in the SU(4)
Heisenberg model on the honeycomb lattice, with algebraic decay of
correlations. Furthermore, for the SU(3) case, I will discuss the competition
between ordered and plaquette states. "
