We analyze the PVLAS results using a chameleon field whose properties depend on the environment. We find that, assuming a runaway bare potential V(phi) and a universal coupling to matter, the chameleon potential is such that the scalar field can act as dark energy. Moreover, the chameleon-field model is compatible with the CERN Axion Solar Telescope results, fifth-force experiments, and cosmology.
我们使用一种性质取决于环境的变色龙场来分析PVLAS实验结果。我们发现，假设存在一个跑动的裸势V(φ)以及与物质的普适耦合，变色龙势使得标量场能够充当暗能量。此外，变色龙场模型与欧洲核子研究中心轴子太阳望远镜的结果、第五种力实验以及宇宙学是兼容的。
