DOI: 10.1088/1742-5468/ac0f6c
Abstract: A spin system with long-range interacting particles is considered. The initial states of the particles are chosen uniformly at random and they are located at the nodes of a flat torus (Z/hZ)2 . Each node… read more here.

DOI: 10.1142/s0219887820500309
Abstract: We consider a two-spin system of XXX Heisenberg type submitted to an external magnetic field. Using the associated ℂP3 geometry, we investigate the dynamics of the system. We explicitly give the co... read more here.
