Chiral critical behavior in two dimensions from five-loop renormalization-group expansions
P. Calabrese, E. V. Orlov, P. Parruccini +1
We analyse the critical behavior of two-dimensional N-vector spin systems with noncollinear order within the five-loop renormalization-group approximation. The structure of the RG…

Chiral phase transitions: focus driven critical behavior in systems with planar and vector ordering
P. Calabrese, P. Parruccini, A. I. Sokolov
The fixed point that governs the critical behavior of magnets described by the -vector chiral model under the physical values of () is shown to be a stable focus bo…
