低能nuclear fusion的相干动力学

Coherence dynamics in low-energy nuclear fusion

Iain Lee, Alexis Diaz-Torres

摘要:

基于开放量子系统理论,用动态耦合道密度矩阵方法描述了低能核聚变反应。这是第一次与能量投影方法相结合,允许计算能量分辨的聚变概率。结果是基准对使用静态薛定谔动力学计算,并显示出良好的协议。通过对熵、能量耗散和相干性的计算,验证了该方法的有效性.很明显,量子退相干的存在并不影响融合概率。该框架为利用热环境进行量子热力学研究提供了基础。

英文摘要:

Low-energy nuclear fusion reactions have been described using a dynamical coupled-channels density matrix method, based on the theory of open quantum systems. For the first time, this has been combined with an energy projection method, permitting the calculation of energy resolved fusion probabilities. The results are benchmarked against calculations using stationary Schrödinger dynamics and show excellent agreement. Calculations of entropy, energy dissipation and coherence were conducted, demonstrating the capability of this method. It is evident that the presence of quantum decoherence does not affect fusion probability. This framework provides a basis for quantum thermodynamic studies using thermal environments.
