电磁场第三量子化的实验验证

Experimental test of the third quantization of the electromagnetic field

J. D. Franson

摘要:

电磁场的每个模式$\small{j}$在数学上等效于由正交表示中的波函数$\small{ψ_j(x_j)}$描述的谐振子。最近引入了一种方法,其中波函数$\small{ψ_j(x_j)}$被进一步量化以产生场算子$\small{{\hat ψ}_j(x_j)}$ [J.D. Franson,Phys.Rev.A104,063702(2021)]。这种方法允许量子光学和量子电动力学的推广基于一个未知的混合角$\smallγ$,有点类似于卡比博角或温伯格角。如果是$\small{γ=0}$,则该理论等价于传统的量子电动力学,而如果是$\small{γ\neq0}$,则该理论预言了一种新的非弹性光子散射形式。在这里,我们报告的光学散射实验的结果,设置在99%的置信水平上界的$\small{γ\leq 1.93 \times 10^{-4}}$,提供了由现场操作员$\small{{\hat ψ}_j(x_j)}$创建的粒子具有可忽略的质量。如果这些粒子的质量非常大,则需要进行高能实验来验证理论。

英文摘要:

Each mode $\small{j}$ of the electromagnetic field is mathematically equivalent to a harmonic oscillator described by a wave function $\small{ψ_j(x_j)}$ in the quadrature representation. An approach was recently introduced in which the wave function $\small{ψ_j(x_j)}$ was further quantized to produce a field operator $\small{{\hat ψ}_j(x_j)}$ [J.D. Franson, Phys. Rev. A 104, 063702 (2021)]. This approach allows a generalization of quantum optics and quantum electrodynamics based on an unknown mixing angle $\smallγ$ that is somewhat analogous to the Cabibbo angle or the Weinberg angle. The theory is equivalent to conventional quantum electrodynamics if $\small{γ=0}$, while it predicts a new form of inelastic photon scattering if $\small{γ\neq0}$. Here we report the results of an optical scattering experiment that set an upper bound of $\small{γ\leq 1.93 \times 10^{-4}}$ at the 99% confidence level, provided that the particles created by the field operator $\small{{\hat ψ}_j(x_j)}$ have negligible mass. High-energy experiments would be required to test the theory if the mass of these particles is very large.
