چکیده
We consider the overlap of Bethe vectors $$XXX$$ spin chain with a diagonal twist and modified general twist. find determinant representation for this under one additional condition on parameters. Such objects arise in calculations nonequilibrium physics.

Drinfeld Twists and Symmetric Bethe Vectors of Supersymmetric Fermion Models
We construct the Drinfeld twists (factorizing F -matrices) of the gl(m|n)invariant fermion model. Completely symmetric representation of the pseudoparticle creation operators of the model are obtained in the basis provided by the F -matrix (the F -basis). We resolve the hierarchy of the nested Bethe vectors in the F -basis for the gl(m|n) supersymmetric model.
متن کاملSequential Bethe Vectors and the Quantum Ernst System * )
We give a brief review on the use of Bethe ansatz techniques to construct solutions of recursive functional equations which emerged in a bootstrap approach to the quantum Ernst system. The construction involves two particular limits of a rational Bethe ansatz system with complex inhomogeneities. First, we pinch two insertions to the critical value. This links Bethe systems with different number...
متن کاملBAC Overlap Identification Based on Bit-Vectors
There is no software that accurately calculates the overlap of two BACs fast enough for application to thousands of cases in turn. The problems include unacceptably low speed of dynamic programming algorithms for sequences of the considered size and failure of the faster local alignment methods to identify complete sequence overlaps. Lower sequence quality at both BAC ends and internal differen...
متن کاملThe Monodromy of Real Bethe Vectors for the Gaudin Model
The Bethe algebras for the Gaudin model act on the multiplicity space of tensor products of irreducible glr-modules and have simple spectrum over real points. This fact is proved by Mukhin, Tarasov and Varchenko who also develop a relationship to Schubert intersections over real points. We use an extension to M0,n+1(R) of these Schubert intersections, constructed by Speyer, to calculate the mon...
متن کاملComparison Results Between Usual Backpropagation and Modified Backpropagation with Weighting: Application to Radar Detection
This paper presents some relevant results of a novel variant of the Backpropagation Algorithm to be applied during the Multilayer Perceptrons learning phase. The novelty consists in a weighting operation when the MLP learns the weights. The purpose is to modify the Mean Square Error objective giving more relevance to less frequent training patterns and resting relevance to the frequent ones. Th...
