Symmetry breaking in low-dimensional SU(N) antiferromagnets
Alexei K. Kolezhuk · RWTH Publications (RWTH Aachen) · 2008
Consequences of explicit symmetry breaking in a physically motivated model of SU(N) antiferromagnet in spatial dimensions one and two are studied. It is shown that the case N=3, which can be realized in spin-1 cold atom systems, displays special properties distinctly different from those for N>=4. Qualitative form of the phase diagram depending on the model parameters is given.
