A Class of N-body Problems With Nearest And Next-to-Nearest Neighbour Interactions
We obtain the exact ground state and a part of the excitation spectrum in one dimension on a line and the exact ground state on a circle in the case where N particles are interacting via nearest and nextto-nearest neighbour interactions. Further, using the exact ground state, we establish a mapping between these N -body problems and the short-range Dyson models introduced recently to model inte...
متن کاملA nucleotide substitution model with nearest-neighbour interactions
MOTIVATION It is well known that neighbouring nucleotides in DNA sequences do not mutate independently of each other. In this paper, we introduce a context-dependent substitution model and derive an algorithm to calculate the likelihood of sequences evolving under this model. We use this algorithm to estimate neighbour-dependent substitution rates, as well as rates for dinucleotide substitution...
متن کاملContinuous- and First-order Phase Transitions in Ising Antiferromagnets with Next-nearest- Neighbour Interactions
Both the square and triangular Ising antiferromagnetic systems with next-nearest neighbour interactions are studied by a new efficient entropic scheme. Using the energy distribution and order parameter’s fourth order cumulant it is illustrated that the two models behave quite differently. For the square model we establish strong numerical evidence showing a continuous transition scaling, wherea...
متن کاملEnhanced Nearest Neighbour
Multimedia databases usually deal with huge amounts of data and it is necessary to have an indexing structure such that eecient retrieval of data can be provided. R-Tree with its variations, is a commonly cited indexing method. In this paper we propose an improved nearest neighbor search algorithm on the R-tree and its variants. The improvement lies in the removal of two hueristics that have be...
متن کاملMicrocanonical entropy of the spherical model with nearest-neighbour interactions
For the spherical model with nearest-neighbour interactions, the microcanonical entropy s(ε,m) is computed analytically in the thermodynamic limit for all accessible values of the energy ε and the magnetization m per spin. The entropy is found to be a concave function, implying that the microcanonical and the canonical ensemble are equivalent, despite the long-range nature of the spherical cons...
