Spread of Entanglement in Generalized Kicked Ising Chain
Tanay Pathak, Hiromi Ebisu, Tomaž Prosen
We investigate the dynamics of entanglement in a generalized version of the kicked Ising chain, extending the model from the standard qubit case (local dimension ) to higher l…
-Body Range : Exact Order-Range Mapping and Dual-Unitarity
Tanay Pathak
We introduce and study a periodically kicked version of a one-dimensional spin- Ising model with contiguous -body interactions. At specific interaction strengths of the mod…
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…
