Domain State of the ANNNI model in Two Dimensions
Fumitaka Matsubara, Takayuki Shirakura, Nobuo Suzuki
We have examined the spin ordering of an axial next-nearest-neighbor Ising (ANNNI) model in two dimensions (2D) near above the antiphase ( phase). We considered…
Absence of a classical long-range order in Heisenberg antiferromagnet on triangular lattice
Nobuo Suzuki, Fumitaka Matsubara, Sumiyoshi Fujiki +1
We study the quantum phase transition of an anisotropic Heisenberg antiferromagnet on a triangular lattice. We calculate the sublattice magnetizat…
Kosterlitz-Thouless Phase Transition of the ANNNI model in Two Dimensions
T. Shirakura, F. Matsubara, N. Suzuki
The spin structure of an axial next-nearest-neighbor Ising (ANNNI) model in two dimensions (2D) is a renewed problem because different Monte Carlo (MC) simulation methods predicted…
Phase diagrams of the S=1/2 quantum antiferromagnetic XY model on the triangular lattice in magnetic fields
Nobuo Suzuki, Fumitaka Matsubara
We study the S=1/2 quantum antiferromagnetic XY model on finite triangular lattices with N sites in both longitudinal and transverse magnetic fields. We calculate physical quantiti…
