论文摘要
Bose - 在血浆填充的微腔内传播的有限数量的光子的凝结。非零化学电位由电子提供，该电子诱导有限的光子质量允许发生凝结。我们得出一个模拟光子模式占用量的演变的方程式，将康普顿散射视为热化机理。光子光谱的动力学演化是数值求解的，我们发现逼真的等离子体密度的缩合证据，$ n_e \ sim 10^{14} -10^{15} \; \ text {cm}^{ - 3} $，与微质量技术兼容。临界温度在光子的数量中几乎是线性的，我们发现在微腔 - plasma温度下，高冷凝水分数对于实验合理的腔长（$ 100-500 \;μ$ m）和光子数（$ 10^{10} -10} -10} -10^{12} $）。
Bose--Einstein condensation of a finite number of photons propagating inside a plasma-filled microcavity is investigated. The nonzero chemical potential is provided by the electrons, which induces a finite photon mass allowing condensation to occur. We derive an equation that models the evolution of the photon-mode occupancies, with Compton scattering taken into account as the mechanism of thermalization. The kinetic evolution of the photon spectrum is solved numerically, and we find evidences of condensation for realistic plasma densities, $n_e\sim 10^{14} - 10^{15}\; \text{cm}^{-3}$, compatible with microplasma technology. The critical temperature is almost linear in the number of photons, and we find high condensate fractions at microcavity-plasma temperatures, for experimentally reasonable cavity lengths ($ 100-500 \; μ$m) and photon numbers ($10^{10}-10^{12}$).
