Algebraic Bethe ansatz for the quantum group invariant open XXZ chain at roots of unity

Nuclear Physics B, 2016
For generic values of q, all the eigenvectors of the transfer matrix of the Uqsl(2)-invariant open spin-1/2 XXZ chain with finite length N can be constructed using the algebraic Bethe ansatz (ABA) formalism of Sklyanin. However, when q is a root of unity

Eigenvectors of random matrices: A survey [PDF]

, 2016
Eigenvectors of large matrices (and graphs) play an essential role in combinatorics and theoretical computer science. The goal of this survey is to provide an up-to-date account on properties of eigenvectors when the matrix (or graph) is random.Comment ...

A note on the eigensystem of the covariance matrix of dichotomous Guttman items

Frontiers in Psychology, 2015
We consider the sample covariance matrix for dichotomous Guttman items under a set of uniformity conditions, and obtain closed-form expressions for the eigenvalues and eigenvectors of the matrix.

Comprehensive Study of Free Vibration of Rectangular Mindlin’s Plates with Rotationally Constrained Edges Using Dynamic Timoshenko Trial Functions

Engineering Transactions, 2018
A comprehensive theoretical study of the free vibration of rotationally restrained rectangular uniform isotropic Mindlin’s plate is presented. The plate mode shape is assumed to be a weighted combination of the product of the Timoshenko beam functions in

AN EIGEN-APPROACH FOR JOINT ESTIMATION OF DIRECTION-OF-ARRIVAL AND FREQUENCY OF AN UNKNOWN NUMBER OF SIGNALS

Jordanian Journal of Computers and Information Technology, 2020
An accurate method for estimating the direction-of-arrival (DOA) jointly with the frequencies of an unknown number of source signals is proposed using the Eigen-approach. Using the minimum eigenvalues of the autocorrelation matrices produces both the DOA
