We propose a novel tridiagonalization approach for non-Hermitian random matrices and Hamiltonians using singular value decomposition (SVD). This technique leverages the real and non-negative nature of singular values, bypassing the complex eigenvalue

In this work, we relate the growth rate of Krylov complexity in the boundary to the radial momentum of an infalling particle in AdS geometry. We show that in general AdS black hole background, our proposal captures the universal behaviors of Krylov c

Recursion methods such as Krylov techniques map complex dynamics to an effective non-interacting problem in one dimension. For example, the operator Krylov space for Floquet dynamics can be mapped to the dynamics of an edge operator of the one-dimens

Krylov complexity is an attractive measure for the rate at which quantum operators spread in the space of all possible operators under dynamical evolution. One expects that its late-time plateau would distinguish between integrable and chaotic dynami

We present a matrix product operator (MPO) construction based on the tensor hypercontraction (THC) format for ab initio molecular Hamiltonians. Such an MPO construction dramatically lowers the memory requirement and cost scaling of Krylov subspace me

Quantum machine learning utilizes the high-dimensional space of quantum systems, attracting significant research interest. This study employs Krylov complexity to analyze task performance in quantum machine learning. We calculate the spread complexit

In this work, we investigate the Krylov complexity in quantum optical systems subject to time--dependent classical external fields. We focus on various interacting quantum optical models, including a collection of two--level atoms, photonic systems a
