2018-12-15 | Breaking the bonds of weak coupling: the dynamic causal modelling of oscillator amplitudes | Models of coupled oscillators are useful in describing a wide variety of
phenomena in physics, biology and economics. These models typically rest on the

coupling and the ... | 0311546v2 |
2004-02-16 | Selfduality for coupled Potts models on the triangular lattice | We present selfdual manifolds for coupled Potts models on the triangular
lattice. We exploit two different techniques: duality followed by decimation,
and mapping to a related loop model. The latter technique is found to be
superior, and it allows to include three-spin couplings. Starting from three
coupled models, suc... | 0402420v1 |
