Magnetic field-induced degenerate ground state in the classical antiferromagnetic XX model on the icosahedron
N. P. Konstantinidis
The ground state of the classical antiferromagnetic XX model in a magnetic field is calculated for spins mounted on the vertices of the icosahedron. The magnetization is characteri…
Local variations of the magnetization effected by an external field in molecular rings
N. P. Konstantinidis
It is shown that an external magnetic field generates local variations of the classical ground-state magnetization in molecular rings of antiferromagnetic icosahedra with isotropic…
Origin of the classical magnetization discontinuities of the dodecahedron
N. P. Konstantinidis
The classical antiferromagnetic Heisenberg model on the dodecahedron has been shown to have three magnetization discontinuities in an external field. Here it is shown that the high…
S=2 quantum magnetization discontinuities proportional in number to the spin s in C: Origin and the role of symmetry
N. P. Konstantinidis
The quantum antiferromagnetic Heisenberg model on the fullerene C in a magnetic field has ground-state magnetization discontinuities with as a function of the…
Classical magnetization of a four-dimensional Platonic solid
N. P. Konstantinidis
The 600-cell is a regular 4-polytope that is a four-dimensional analog of a Platonic solid. Three-dimensional Platonic solids with icosahedral -symmetry have been shown to hav…
Competition between frustration and spin dimensionality in the classical antiferromagnetic -vector model with arbitrary
N. P. Konstantinidis
A new method to characterize the strength of magnetic frustration is proposed by calculating the minimum dimensionality of the absolute ground states of the classical nearest-neigh…
