Conventional description of Unconventional Coulomb-Crystal phase transitions in three-dimensional classical O(N) spin-ice | | Cenke Xu
; | | Date: |
16 Nov 2009 | | Abstract: | We study the phase transition between the high temperature Coulomb phase and
the low temperature staggered crystal phase in three dimensional classical O(N)
spin-ice model. Compared with the previously proposed CP(1) formalism on the
Coulomb-crystal transition of the classical dimer model, our description based
on constrained order parameter is more conventional, due to a fundamental
difference between the O(N) and the dimer model. A systematic epsilon and 1/N
expansion are used to study the universality class of the phase transition, and
a stable fixed point is found based on our calculations for large enough N. | | Source: | arXiv, 0911.2828 | | Services: | Forum | Review | PDF | Favorites | |
