光[一个无质量的U(1)规范玻色子]的存在是自然界尚未解开的谜团之一。我们提出光起源于真空中的某些量子序。我们在晶格上构造量子自旋模型，以证明某些量子序可以在不破坏任何对称性和不进行任何微调的情况下产生光。通过我们的模型，我们证明了光的存在可以简单地看作是多自由度系统中的量子相干现象。在最初不包含规范场的强关联量子系统中，无质量规范涨落普遍而自然地出现。
The existence of light [a massless U(1) gauge boson] is one of the unresolved mysteries in nature. We propose that light is originated from certain quantum orders in our vacuum. We construct quantum spin models on lattice to demonstrate that some quantum orders can give rise to light without breaking any symmetries and without any fine-tuning. Through our models, we show that the existence of light can simply be a phenomenon of quantum coherence in a system with many degrees of freedom. Massless gauge fluctuations appear commonly and naturally in strongly correlated quantum systems which originally contain no gauge fields.
