The problem of joint approximate diagonalization of symmetric real matrices is addressed. It is reduced to an optimization problem with the restriction that the matrix of the similarity transformation ...

Abstract: In order to fully benefit from multiple-input multiple-output (MIMO) channels, multiuser techniques are adopted in the 3rd generation partner project (3GPP) long term evolution (LTE) ...

Implement state-of-the-art iterative eigensolvers (Lanczos, Davidson, LOBPCG) optimized for momentum-conserved Hamiltonians, exploiting block-diagonal structure for memory efficiency and parallel ...

This work presents the application of the lesser-known yet significant Sommerfeld-Watson transformation (SWT) for the analytical diagonalization of specific Hamiltonians in condensed matter physics.

Abstract: The 3 × 3 identity matrix is additively and multi-plicatively factorized into unitary scaffolding matrices, using the Frobian-Schmidt matrix norm. The decomposition, being ambiguous, leads ...
