Four-weight Spin Models and Jones Pairs
We introduce and discuss Jones pairs. These provide a generalization and a new approach to the four-weight spin models of Bannai and Bannai. We show that each four-weight spin model determines a “dual” pair of association schemes. 1. Jones Pairs The space of k × k matrices acts on itself in three distinct ways: if C ∈ Mk(F), we can define endomorphisms XC , ∆C and YC by XC(M) = CM, ∆C(M) = C ◦M...
متن کاملCompleteness of classical spin models and universal quantum computation
We study mappings between distinct classical spin systems that leave the partition function invariant. As recently shown in [Phys. Rev. Lett. 10
متن کاملCritical behavior of ferromagnetic spin models with aperiodic exchange interactions
We review recent investigations of the critical behavior of ferromagnetic q-state Potts models on a class of hierarchical lattices, with exchange interactions according to some deterministic but aperiodic substitution rules. The problem is formulated in terms of exact recursion relations on a suitable parameter space. The analysis of the fixed points of these equations leads to a criterion to g...
متن کاملUniversal Lax Pair for Generalised Calogero–Moser Models
In this talk we introduce generalised Calogero–Moser models and demonstrate their integrability by constructing universal Lax pair operators. These include models based on non-crystallographic root systems, that is the root systems of the finite reflection groups, H3, H4, and the dihedral group I2(m), besides the well-known ones based on crystallographic root systems, namely those associated wi...
متن کاملSpin Foam Models
While the use of spin networks has greatly improved our understanding of the kinematical aspects of quantum gravity, the dynamical aspects remain obscure. To address this problem, we deene the concept of a `spin foam' going from one spin network to another. Just as a spin network is a graph with edges labeled by representations and vertices labeled by intertwining operators, a spin foam is a 2-...
