Geometric-phase control of Krylov complexity in adiabatic dynamics
Han-Qi Zheng, Peng-Zhang He, Lei-Hua Liu +1
We show that geometric phases accumulated during adiabatic evolution can be converted into observable interference in Krylov space, leading to a geometric-phase-dependent Krylov os…
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…
Inflationary power spectrum from the Lanczos algorithm
Ke-Hong Zhai, Lei-Hua Liu, Hai-Qing Zhang
The generalized Lanczos algorithm can provide a universal method for constructing the wave function under the group structure of Hamiltonian. Based on this fact, we obtain an open…
