A Bogoliubov-ratio framework for quantum-information diagnostics of time-dependent two-mode Boson System
Shi-Cheng Liu, Lei-Hua Liu, Bichu Li +2
We formulate a compact dynamical representation of quantum-information diagnostics for time-dependent two-mode bosonic systems in terms of the Bogoliubov ratio $λ_k(η)=β_k(η)/α_k(η…

Krylov Complexity in Non-Inertial Quantum Systems
Ming-Qi Ma, Shi-Cheng Liu, Lei-Hua Liu +1
This study formulates observer-dependent Krylov spreading for non-inertial quantum systems driven by linear Bogoliubov transformations. Starting with the closed single Rindler-pair…
