The effect of finite mass in cavity QED calculations

Ankita Nair, Vikas Bharti, Yetmgeta S. Aklilu, Kalman Varga

AI总结:

本文利用 Pauli-Fierz 哈密顿量分析 He、H$^-$ 和 H$_2^+$ 系统,揭示腔 QED 中有限核质量及微弱光耦合对结合能的显著影响。

摘要:

本文采用 Pauli-Fierz 哈密顿量,研究腔量子电动力学(cavity QED)中耦合光-物质系统的有限核质量效应。研究考察了 He 原子、H$^-$ 离子和 H$_2^+$ 离子三种不同系统。结果表明,结合能随耦合强度变化的行为存在虽小但显著的差异。研究发现,与光耦合的概率非常小,但即使是这种微小耦合,也会对这些系统的能量产生非常强烈的影响。

英文摘要:

The effect of finite nuclear mass is investigated in coupled light matter systems in cavity quantum electrodynamics (cavity QED) using the Pauli-Fierz Hamiltonian. Three different systems, the He atom, the H$^-$ ion and the H$_2^+$ ion is investigated. There are small, but significant differences in the behavior of the binding energies as the function of the coupling strength. The probability of coupling to light is found to be very small but even this small coupling has a very strong effect on the energies of the systems.
