I’ve understood that a dense/exact diagonalization method (e.g., LinearAlgebra.jl's eigen()) is currently used for diagonalizing projected Hamiltonians during the sweeps (please correct me if I’m ...

Abstract: We propose a regularized channel diagonalization method for a joint transmit-receive linear optimization in the downlink of a multiuser multiple-input multiple-output (MIMO) communication ...

Abstract: Pattern synthesis of nonuniform antenna arrays has drawn significant attention because of its wide applications. With the aim of reducing the number of elements in linear and planar arrays, ...

Quantum diagonalization methods are a new class of techniques that are being developed for Hamiltonian simulation. Check Sample based Krylov Quantum Diagonalization to get a basic idea of this type of ...

Recent developments have shown that one can get around the difficulties of finding the eigenvalues and eigenmodes of the large systems studied with high performance computation by using broadly ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

The criticality of the (2+1)-dimensional XY model is investigated with the numerical diagonalization method. So far, it has been considered that the diagonalization method would not be very suitable ...
