从热力学极限到小光子数的光子玻色-爱因斯坦凝聚

Bose-Einstein condensation of photons from the thermodynamic limit to small photon numbers

Robert A. Nyman, Benjamin T. Walker

摘要:

光子可以通过从荧光染料多次散射而在室温下达到热平衡。通过将光和染料限制在微腔中,设定最小能量,然后光子可以显示玻色-爱因斯坦凝聚。我们在这里提出的物理原理光子热化和凝聚,并回顾有关文献的主题。然后,我们探索的“小”制度,很少的光子需要冷凝。我们比较热平衡结果的速率方程模型的微激光器,其中包括自发发射到腔中,我们注意到,小系统的阈值的定义中的模糊性。

英文摘要:

Photons can come to thermal equilibrium at room temperature by scattering multiple times from a fluorescent dye. By confining the light and dye in a microcavity, a minimum energy is set and the photons can then show Bose-Einstein condensation. We present here the physical principles underlying photon thermalization and condensation, and review the literature on the subject. We then explore the `small' regime where very few photons are needed for condensation. We compare thermal equilibrium results to a rate-equation model of microlasers, which includes spontaneous emission into the cavity, and we note that small systems result in ambiguity in the definition of threshold.
