C++ heavily templated code for single- and many-body hamiltonians with inbuilt chaotic indicators, spectral functions and many more. The algebra is based on the ARMADILLO C++ package.

A deflated and restarted Lanczos algorithm to solve hermitian linear systems, and at the same time compute eigenvalues and eigenvectors for application to multiple right-hand sides, is described. For ...

We explore improving sparse matrix operation efficiency using the Compressed Sparse Row (CSR) format. In the process, we explore an application of the Lanczos algorithm in efficiently computing a ...

Abstract: The global Lanczos algorithm for solving the RLCG interconnect circuits is presented in this paper. This algorithm is an extension of the standard Lanczos algorithm for multiple-inputs ...

Abstract: In this paper, we propose the application of the L-curve and curvature to the super resolution image restoration problem. L-curve criterion is used to estimate regularization parameters.

This Letter introduces a method for determining the energy spectrum of lattice quantum chromodynamics by applying the Lanczos algorithm to the transfer matrix and using a bootstrap generalization of ...

The Nature Index 2026 Research Leaders reveal the leading institutions and countries/territories in the natural sciences, health sciences, applied sciences and social sciences, according to their ...

Time evolution and scattering simulation in phenomenological models are of great interest for testing and validating the potential for near-term quantum computers to simulate quantum field theories.
