Krylov space approach to Singular Value Decomposition in non-Hermitian systems

Pratik Nandy, Tanay Pathak, Zhuo-Yu Xian +1

We propose a tridiagonalization approach for non-Hermitian random matrices and Hamiltonians using singular value decomposition (SVD). This technique leverages the real and non-nega…

Probing quantum chaos through singular-value correlations in sparse non-Hermitian SYK model

Pratik Nandy, Tanay Pathak, Masaki Tezuka

Utilizing singular value decomposition, our investigation focuses on the spectrum of the singular values within a sparse non-Hermitian Sachdev-Ye-Kitaev (SYK) model. Unlike the com…

Analytic continuations and numerical evaluation of the Appell $F_{1}$ , $F_{3}$ , Lauricella $F_{D}^{(3)}$ and Lauricella-Saran $F_{S}^{(3)}$ and their Application to Feynman Integrals

Souvik Bera, Tanay Pathak

We present our investigation of the study of two variable hypergeometric series, namely Appell $F_{1}$ and $F_{3}$ series, and obtain a comprehensive list of its analytic continuat…
