Canonical solution of a system of long-range interacting rotators on a lattice
نویسندگان
چکیده
The canonical partition function of a system of rotators (classical X-Y spins) on a lattice, coupled by terms decaying as the inverse of their distance to the power alpha, is analytically computed. It is also shown how to compute a rescaling function that allows us to reduce the model, for any d-dimensional lattice and for any alpha<d, to the mean-field (alpha=0) model.

متن کاملSynchronization for discrete mean-field rotators
We analyze a non-reversible mean-field jump dynamics for discrete q-valued rotators and show in particular that it exhibits synchronization. The dynamics is the meanfield analogue of the lattice dynamics investigated by the same authors in [30] which provides an example of a non-ergodic interacting particle system on the basis of a mechanism suggested by Maes and Shlosman [37]. Based on the cor...
متن کامل0 Universal behavior in the static and dynamic properties of the α - XY model
The α-XY model generalizes, through the introduction of a power-law decaying potential, a well studied mean-field hamiltonian model with attractive long-range interactions. In the α-model, the interaction between classical rotators on a lattice is gauged by the exponent α in the couplings decaying as r, where r are distances between sites. We review and comment here a few recent results on the ...

متن کاملPoisson Lie Group Symmetries for the Isotropic Rotator
We find a new Hamiltonian formulation of the classical isotropic rotator where left and right SU(2) transformations are not canonical symmetries but rather Poisson Lie group symmetries. The system corresponds to the classical analog of a quantum mechanical rotator which possesses quantum group symmetries. We also examine systems of two classical interacting rotators having Poisson Lie group sym...
