Lifting of Multiphase Degeneracy by Quantum Fluctuations
A. B. Harris, C. Micheletti, J. M. Yeomans
We study the effect of quantum fluctuations on the multiphase point of the Heisenberg model with first- and second-neighbor competing interactions and strong uniaxial spin anisotro…

An Upsilon Point in a Spin Model
C. Micheletti, F. Seno, J. M. Yeomans
We present analytic evidence for the occurrence of an upsilon point, an infinite checkerboard structure of modulated phases, in the ground state of a spin model. The structure of t…
