量子阻尼振子的退相干

Decoherence of Quantum Damped Oscillators

Sang Pyo Kim, Ademir E. Santana, F. C. Khanna

摘要:

研究了两个模型振子中的量子耗散,Caldirola-Kanai(CK)振子是一个具有一个自由度的开放系统,Bateman-Feshbach-Tikochinsky(BFT)振子是一个具有两个自由度的封闭系统.虽然这些振子描述了相同的经典阻尼运动,但CK振子保持了量子相干性,而BFT振子的阻尼子系统同时表现出量子退相干和经典关联。此外,BFT振荡器的放大子系统表现出相同程度的量子退相干和经典关联。

英文摘要:

Quantum dissipation is studied within two model oscillators, the Caldirola-Kanai (CK) oscillator as an open system with one degree of freedom and the Bateman-Feshbach-Tikochinsky (BFT) oscillator as a closed system with two degrees of freedom. Though these oscillators describe the same classical damped motion, the CK oscillator retains the quantum coherence, whereas the damped subsystem of the BFT oscillator exhibits both quantum decoherence and classical correlation. Furthermore the amplified subsystem of the BFT oscillator shows the same degree of quantum decohernce and classical correlation.
