研究成果
The study demonstrates that driving frequencies play a crucial role in sustaining entanglement among coupled quantum oscillators, even at high temperatures. The base frequency determines characteristic parameters of entanglement dynamics, while relative driving frequencies and amplitudes influence the occurrence of entanglement. Frequency analysis of ripples in logarithmic entropy provides insights into the dynamics of entanglement in systems with multiple coupling terms.
